Hi Community,
I'm seeking guidance on a few doubts about the N4032 configuration issues. Although I have taken networking classes with Cisco switches still new to the field, never configured N4032 before. Ok, this is the situation: we're upgrading our network with 2 N4032 switches connected to a Vxrail appliance and I have been assigned the switches configuration, which is:
- Create Vlan for Management (this have to be routable), VSAN, Vmotion and production environment and assign ports, ip addresses to them. All Vlan's are tagged.
- Ports connected to the appliance have to run in trunk mode and allow tagged traffic for their respective vlan. Other than Management traffic, all traffic is isolated.
- ipv4 / ipv6 multicast has to be enable thru MLD and IGMP snooping and querier.
- Uplink port to backbone has to allow vlans traffic.
Now, these are the issues and doubts:
- We're planning to use one switch as master and the other as backup and I read that we can use the QSPF modules for stacking and use the auto sync command so the backup switch get the master configuration. Is this correct? Please elaborate on how to do this.
- When #sho interfaces status, I see default vlan 1 in parenthesis in the same ports assigned to other vlans. Why?
- When #sho run I can see MLD and IGMP snooping querier enabled for the required vlan. Do I need to do enable something else?
- When I plug the uplink port to the backbone switch, the port gets disabled because of a looping caused by STP sent by the switch I'm working on. What am I missing here?
- When I test the vlan connection pinging 2 laptops with firewall off and within the vlan ip addreses range, I get destination host unreachable.
This is result of my #sho run:
