I have a setup where 2 redundant Nexus3Ks are connected to 2 redundant Catalyst3750.
Each Catalyst is connected to both Nexus on a port channel. On Nexus side vPC is configured.
There are already 4 vlans working on the link between Catalyst and Nexus.
Now I want to add a 5th VLAN, can it be done without impacting any traffic? What could be the impact? Any suggestions?
Adding VLAN on port channel is enough?
Current configurations are below
#############################
interface port-channel10 <---Port Channel towards other Nexus
description Po10 to FDP-R02
switchport mode trunk
switchport trunk allowed vlan 162-168,210-238,246-257,260-261,501-506,509-517,851-852,1253
spanning-tree port type network
no negotiate auto
vpc peer-link
interface port-channel3 <---Port Channel (vpc based) towards Catalyst
description Po3 to Cat3
switchport mode trunk
switchport trunk allowed vlan 246,249,252,852
spanning-tree port type edge trunk
no negotiate auto
vpc 3
interface port-channel4 <---Port Channel (vpc based) towards Catalyst
description Po4 to Cat4
switchport mode trunk
switchport trunk allowed vlan 246,249,252,852
spanning-tree port type edge trunk
no negotiate auto
vpc 4
Now the new VLAN need to be added is 258. And I have prepared below configurations.
Can you please tell me with below configurations if there can be any impact? Or regardless of the below configurations what can be the impact?
vlan 258
name prv_cms
interface port-channel10
switchport trunk allowed vlan 162-168,210-238,246-258,260-261,501-506,509-517,851-852,1253
interface port-channel3
switchport trunk allowed vlan 246,249,252,852,258
interface port-channel4
switchport trunk allowed vlan 246,249,252,852,258
