untagged or tag port configuration for Equallogic DCB

$
0
0

Hi there,

We've used to configure switch ports that are connected to Equallogic as access mode to carry untagged traffic for iscsi vlan. The reason being is EQL didn't support vlan tagging before. 

I'm a bit confused with "DCB" configuration. Now on, do we have to tag the iscsi traffic on EQL ports if DCB is configured?

Thanks,

 


VLAN Assistance Needed

$

Greetings! I need to create a network that has 10 separate VLANs (only 3ports/VLAN)  that can share one internet connection, but have no inter-VLAN visibility. What would be the best manner in putting this together? Private VLANs? Which PowerConnect Switch would be the best to go with for something like this?

Thank you!

PC 6248P Ip helper-address dhcp

$

I am working on getting a vlan setup for our new shoretel phones. I have 2 PC 6248p stacked. The first unit is primarily used for desktops servers and our wireless APs. The APs are on a vlan (1001 - which is bound to 192.168.3.0/24) but all the other ports are Access and are set to vlan 1 untagged (vlan 1 is the default vlan). Our DHCP server is on 192.168.1.0/24 which is the subnet for the default vlan and has a scope setup for this subnet. It also has a scope set for 10.1.6.0/24 which is the subnet for vlan 200 Unit 2 of the stack has most of its ports set to general mode pvid 200. Vlan 200 interface is set to 10.1.6.1 and VLAN 200 is bound to 10.1.6.0/24 I have DHCP relay enabled globaly and VLAN 200 set for IP helper-address 192.168.1.185 which is my DHCP server. I have tried having my switches in routing mode and with "no ip routing" either way, when devices are plugged into ports with Switchport general pvid 200 the dhcp server is unavailable. When plugged into a port set as untagged then DHCP is available and the device gets a 192.168.1.0/24 address. I need devices plugged into the ports tagged vlan 200 to get assigned address via DHCP in the 10.1.6.0/24 subnet. What am I missing?

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?

Hello,

Want the secure server that are connected to the port of Cisco Catalyst 2960

 The following configuration, any mistake?

Global :
ip dhcp snooping 
ip dhcp snooping vlan X
ip arp inspection vlan X
ip source binding AAAA:BBBB:CCCC vlan X X.X.X.X interface fa0/1 

On fa0/1 port :
switchport access vlan 85
switchport mode access
switchport port-security 
switchport-security maximum 1
switchport port-security violation protect
switchport block multicast
switchport block unicast
ip verify source

That advise me on setting up storm-control broadcast/multicast/unicast (storm-control action shutdown) ?

Thank you very much!


Applying ACLs to an 8132 switch

$

I have a PC8132F switch configured with two VLANs;

  • VLAN 10 - 10.0.0.0/24
  • VLAN 20 - 192.168.0.0/24


IP routing is enabled on the switch and devices on each VLAN communicate with each other as expected. I would like to apply IP ACLs so that VLAN 10 cannot access VLAN 20, but VLAN 20 can access VLAN 10. I've applied an ACL to the switch using the following commands:

access-list vl10 deny ip 10.0.0.0 0.0.0.255 192.168.0.0 0.0.0.255
access-list vl10 permit ip any any
interface vlan 10
ip access-group vl10

After applying, VLAN 10 is blocked from accessing VLAN 20 as intended, but VLAN 20 also loses access to VLAN 10 because the reply traffic from VLAN 10 is being blocked on return.

I've looked over the CLI Reference Guide, but can't see anything about ACLs supporting stateful/established connections to support reply traffic. Can it be done, and if so, how would I go about achieving it?

Thanks

Access port versus general untagged

$

If I set a port to access and the port belongs to the vlan that contains my DHCP server, my device acquires and address instantly.  If the port is set to General and is an untagged member of the same vlan then I don't get an address from my DHCP server.  Why would this be?   

Dell 2824 / Ubiquiti UniFI / Guest WIFI VLAN tag

$
0
0

Hi,

I have a 2824 PowerConnect and two Ubiquiti UniFI APs each of which is wired into a port on the 2824. 

The UniFi APs create wireless networks and share the configuration among all radios. These two APs are publishing two SSIDs, one protected wireless network for staff, another unprotected wireless network for guests. I have the ability to tag either wireless network as I want.

I want to use a VLAN to push traffic through the Dell switch onto a DMZ port in our firewall. 

My initial idea was to:

1. Tag the Guest wireless network with VLAN 11.

2. Leave the Staff wireless network un-tagged.

3. Set trunks on the two ports which terminate the APs to allow untagged and 11.

4. Add an additional port on the 2824 to membership in 11 only.

5. Wire the 11-only port to the DMZ port of my firewall. 

Here are my questions:

1. Can a trunk port allow both un-tagged and ID packets?

2. If so, can I specify a port REJECT untagged packets? (I want to prevent untagged stuff from reaching the DMZ port on the firewall.)

3. Does anyone see a flaw in my set up?

Thanks,

m

Critical Scan: A VxWorks WDB Debug Agent is running on this host.

Received a Critical alert from a Nessus scan today that one of our Dell 6248 PowerConnect switches is running A VxWorks WDB Debug Agent, and is therefore vulnerable. Is there any way to simply disable this service/agent? (VU#362332) refers to an exposed VxWorks debug service (WDB Agent). This service runs over UDP port 17185 and allows complete access to the device, including the ability to manipulate memory, steal data, and ultimately hijack the entire operating system. Solution: Disable the debug agent Description: "Synopsis: Arbitrary commands can be run on this port. Description: A VxWorks WDB Debug Agent is running on this host. Using this service, it is possible to read or write any memory zone or execute arbitrary code on the host. An attacker can use this flaw to take complete control of the affected device.

We deployed a Dell 5424 Switch without proper config documentation.

It is picking up an DHCP and active on the network.

How do I find out what IP it is getting if I know the mac address for the switch?

Slave switch keeps rebooting after unstacking- Dell PowerConnect 6224

$

Hello Everyone; 

I have 2 switches (PowerConnect 6224) stacked together. Since we no longer need them stacked as we got new switches we decided to take the stack cables away and use them as individual switches.

So I tried unstacking the switches first using via CLI but it did not work, simply nothing happens. So I took the stacking cards away from both switches and removed the stacking cables.

Master switch works fine, but the slave keeps rebooting.

I trued the following:

From boot options, I tried reset, restore manufacture settings, format ... They look successful as the config seems like it's gone  and once the switch boots it ask me if I want to run configuration wizard but it will just freeze and reboot. 

is there way to fix it? or the switch is dead? 

All ideas are welcomed

thank you 


High CPU for ipMapForwardingTask

I have a problem with Powerconnect 6248, which appeared recently. Time from time CPU for ipMapForwardingTask rises up to 30-40% instead of normal operation (average 6%) and PINGs to switch raises from 1ms to 50-100ms. Logs show nothing. It last from several dozens seconds to minutes. Then it goes back to its normal stage, but after few hours (or less) repeats again. What could be the reason? Current FW 3.3.1.10

Dell Power Connect 5548 DHCP Relay Not Working

$

Guys,

Ok, so i have a Windows DHCP server. I have setup a new VLAN Scope.

I then assign on my 5548 an IP address for each VLAN, enable DHCP Globally and specify the Windows DHCP server's IP. However none of the Clients connected to the other VLANS besides the one the DHCP server is on, are pulling addresses.

Any ideas?

Here are the configs shown on the switch

ip dhcp relay address 192.168.10.5
ip dhcp relay enable

ip address 192.168.10.230 255.255.255.0

Hello All,

A quick question.

From the above mentioned switch i have 3 vlan's towards the corporate network. Vlan1 is empty.

Can i use VLAN1 for traffic that will not be routed outside of the Switch? Or the optimum scenario would be to create a new vlan.

Thank you in advance..

how to filter default route on rip router

$

Hi

I have two router which are powerconnect 8164F.

they learn both default route from their border router therefore i would like to prevent them to sending defaultroute to each other.

on cisco switch i do the following way

The router are connected though vlan 9

i define a standard acl

ip access-list standard anti-default
deny 0.0.0.0
permit any

and in the router rip directive i wrote in both config

distribute-list anti-default out Vlan9

i could do the same on powerconnect but

i didn't find a way to a standard acl on powerconnect.

i didn't find a way to have different distribution regarding vlans.
