can not create Channel-Group between two switches PC5524

June 24, 2014, 3:59 am

Hi there!
i've two switches Dell PC5524, and i want to create portchannel between them.

The configuration of two switches are as below:

SW01:

!
interface vlan 5
name USERS
!
interface vlan 6
name SERVERS
ip address 192.168.6.1 255.255.255.0
!
interface gigabitethernet1/0/1
channel-group 1 mode on
switchport mode trunk
switchport access vlan 6
!
interface gigabitethernet1/0/2
channel-group 1 mode on
switchport mode trunk
switchport access vlan 6

SW02:

!
interface vlan 5
name USERS
!
interface vlan 6
name SERVERS
ip address 192.168.6.2 255.255.255.0
!
interface gigabitethernet1/0/1
channel-group 1 mode on
switchport mode trunk
switchport access vlan 6
!
interface gigabitethernet1/0/2
channel-group 1 mode on
switchport mode trunk
switchport access vlan 6

Before, the ports gi1/01 and gi1/02...were part of vlan 6.
now, i tried to remove that configuration:
switchport access vlan 6

BUT I CAN NOT DELETE IT.

i tried again, when i put the configuration

channel-group 1 mode auto.

If i use only one port, with no portchannel configuration, and make it run in trunk mode, the two switches communicate normally with each other.

Now, what is my problem? and how can i fix it?
Regards!

Issue configuring MAC ACL on Powerconnect 5524/5548 stack

June 25, 2014, 1:27 am

Hi guys,

I have run into an issue when configuring a MAC ACL using the UI. My setup is a fairly simple stacked set of 2x 5524 and 5x 5548P. All I want to achieve is applying a MAC ACL to every port on every switch which denies access to only a few specific MAC addresses.

Now the ACL itself I have working. I've created an ACL with three ACEs, two of which are deny entries for test MAC addresses, the third of which is an allow all other entry at a much lower priority, like so:

I have then applied this to a few test ports, like so:

Now all of this works swimmingly, I know that without the priority 999 item it blocks all MACs, and with that it still blocks the ones I want blocked without blocking everything else.

My problem is this. When I realised that the first two lines alone would not do what I want as it blocked everything rather than just what I wanted, I went to edit the ACL and add the third shown ACE to it whilst it was still assigned to ports. I was told that I can't edit the ACL as long as it's still bound to a port. Now this to me seems ludicrous. Given that I'm not a competent CLI user and choose to manage my switches in the GUI, and further given that the "copy to, select all" function in the second shown screenshot there doesn't actually function and only actually copies the config to the last selected port in any given selected range, it means that every time I want to make a change to this ACL and add an extra ACE I would need to remove the ACL binding from every port and then manually re-apply the ACL after my edit to all 288 ports... Individually... One at a time...

Just doing a quick estimation here, assuming a fairly quick rate of clicks and the occasional break for a breath or a quick drink, that's approx. 45 minutes to add one MAC address to my ACL. Can't say that particularly floats my boat!

Can someone please let me know if I've missed something here and that there's a way to do this that will actually make it feasible?

Many thanks in advance for any help!

Force10 VLT and fast failover

Forgive me if this belongs somewhere else, but I could not find a Force10 forum. We have a 4820T pair configured as a VLT domain. Our "leaves" are Dell 5548s and 6224s connected via LAGs to the 4820T "spines". It seems in a failure scenario we cannot get our paths back up in less than about 7-8 seconds. In one of the white papers they were showing 1.5 sec path recoveries. What is the determining factor in getting a fast recovery? We have RSTP hello times etc dialed as low as they can go on the PowerConnects FWIW. Is there something else in say LACP etc that we have missed causing the path recovery to be slow?

M1000e with M8024 (problem connecting to switch)

I have a Dell Poweredge M1000E blade chassis with two M8024 switches.

I configured the IP addresses of the M8024 (B1 and B2) from the web CMC.

All ports on the chassis controllers are connected to my network.

I can connect with no problems to the M8024 in B2 slot, but cannot connect / ping / access the M8024 in B1.  I have tried power cycling/reseating the switch but no luck.

Any suggestions?  I have not tried to do anything via SERIAL connection.

Hey there, the latest publically available firmware for these switches is 6.1.2, which has a serious hang problem, that I'm running into on both of my 3024's. You had a new beta release, 6.1.5, that remedied this. The only way to get it is to contact the dell forum/mods. So I am desperately requesting someone send me this firmware! Thank you so much!  I'm about to throw these switches in the trash due to frustration, but v6.1.5 totally fixes this random hang issue so I'd love to go that route instead!

If you have it please email me at <ADMIN NOTE: Email id removed per privacy policy> Thanks!

Providing iSCSI San redundancy with power connect 6224 and equallogic ps 6100 series san

June 27, 2014, 8:03 am

we have 8 servers running hyper v connecting to a equallogic ps 6100 series san. We purchased two power connect 6224 switches and we are currently using one of them successfully as we have two nics from each physical server going to each switch and the san connected to both as well. we must be missing something because when we create the LAG with 4 ports, connect the switches together and connect the second switch to the san, our traffic speeds fall, meaning that we get ping responses over 10ms where with one switch we get the normal less than one ms response time. I really need to put the second switch into production to add redundancy to the network, but I cant figure out what I am missing and why adding the second switch reduces network performance. I would appreciate any help you can give as to how we should setup two 6224 switches between servers with multiple nics and the equallogic ps 6100 san. thanks john

Using 2 Dell 3524s to provide redundancy for servers

We currently have 8 servers, all with dual nics and we are currently using a single unmanaged switch to provide connectivity between these servers and to the firewall LAN interface. We have purchased two Dell 3524 switches and we have two SonicWall NSA 4500s. My question is what should the setup on the two switches be and how should we connect them? 1. im not sure what the config should be, any specifics on the switch? 2. should we interconnect the swtiches creating a lag and putting two or more ports in it? 3. should we team the two nics on the server? placing one nic on the first switch and the second nic on the second switch? or should we leave the switches disconnected from one another, not team the nics and just have one on standby plugged into the LAN port of the failover NSA 4500. We want to provide redundancy so if one of the switches or firewalls go down for any reason we are covered. Im just not sure of the best route to take. Any help in what I should do would be greatly appreciated. Thanks john

Suggested 10G cabling for a LAG on 4 N3048 switches where they are stacked in pairs

June 29, 2014, 6:52 pm
$

Hi,

I've just racked up four N3048 Switches in preparation for the relocation of our EQL iSCSI SAN/Hosts (the actual relocation is not really relevant to this query).

Given the number of ports required and the HA requirements, we've deployed the first two switches as a 'switch' in a stack of 2 with the stacking cables correctly installed.  The second 'switch' is identically cabled as a stack of two units.

The stack will give me two 'switches' with 96 ports each - one in rack A and one in rack B.  This gives me the desired capacity and provides for redundancy (power and physical port).  I don't want to create a 4 switch stack as I would have to reboot all 4 during a firmware upgrade etc.

Given we can now 'pretend' I have two switches (of 96 ports each), I need to address how to connect the LAG cables.  We're using 10G SFP cables with the rear-mounted dual port SFP cards.  

My specific query is on which port on which switch should go to the corresponding other side.  In other words, should I connect the first SFP port on the topmost unit in rack A to the exact same port in rack B,  then continue as second port on topmost switch in rack A to same port in rack B?  [Option 1]

Or, should I be following the same methodology as the stack ports and connect first port topmost in rack A to bottom, last port in rack B so I'm essentially crossing all the switches over?  [Option 2]

Or, third option, Split the connections so first switch, first port goes to same port but lower switch in rack B and same for 2nd port? [Option 3]

Any ideas/experience welcome.  Oh, and if there is a TR on this scenario, I'd love the URL.

Cheers.

EPS-470 power supply and Dell PowerConnect switches - 2 outlets or 1?

I'm doing some network design (which includes racks and PDUs.  In several cases, I need an EPS-470 power supply to provide PoE to all 48 ports on a PowerConnect switch.

I need to know, do I need one outlet for the switch and one for the EPS-470, or after the switch is hooked into the EPS-470 do I just need power hooked into that?  I just need to know whether I need one or two outlets so I plan accordingly for the PDUs.

Connection between two switches connected by L2 layer link is not functional

As a part of my network, I have two switches PowerConnect 6248P connected in trunk mode with several VLANs defined, including one for workstation and one for voice. These two switches are connected with a regular patch cord.


I have to move urgently one switch in another building, I already have a L2 link between the 2 IT rooms (leased line from telco operator). When I connect the two switches using this L2 link, keeping the same configuration on the two switches, the network is not functional anymore. The desktops and phones (all with fixed IPs) connected to the switch that was moved cannot connect to the network.


When inspecting the network traffic, on a desktop connected to the moved switch, we see ARP requests that don't get answers. I had two network engineers working on the issue, and they are puzzled by the fact it doesn't work.


Any idea of where to look ? I don't have enough time to deploy a L3 routing connection between the two locations, which is the next step, but I really need to make this temporary solution work.


Thanks,

Vincent

Connecting 2 'factory default' 5548P switches causes network to go down

Hello, I am running a small network (15 VoIP phones and about 20 workstations and some printers and 8 servers). They are all connected to my 5548P switch and everything works great. We are expanding physically, and I added an additional 5548P to the network and I need to connect the two together. So I did and every time I connect port 48 of one switch to port 48 to the other my network goes down. Both switches still are in factory default mode. I have done no configuration on either one. How do I set up to make them play nice? I don't need anything fancy. My servers will remain in the original location and only about 5 - 8 users will be moving (all with phone and workstation and a few printers). Thanks! Arno Butter
