Hello,
I just added a SVI on a core switch (Catalyst 3750). The VLAN is vlan 370. The core switch that this VLAN is configured on CAN ping the default gateway for this VLAN - 10.37.30.1. I can ping the default gateway from my workstation as well.
There are 3 switches in the mix.
The core switch
AS-01 which is the up linking switch
AS-02 which is the switch that has an Ubuntu server plugged into the Access port for this new VLAN.
PROBLEM: The Ubuntu server cannot ping its default gateway: 10.37.30.1
I am POSITIVE this is because the AS-01 switch in the middle is NOT allowing VLAN 370 into the management domain. It DOES allow the VLAN across the trunk, just not into the management domain as shown here:
Port Vlans allowed on trunk
Gi0/1 1,100,110,310,330,340,350-351,360,370,999
Gi0/3 1,100,110,310,330,340,350-351,360,370,999
Gi0/4 1-4094
Port Vlans allowed and active in management domain
Gi0/1 1,100,110,310,330,340,350-351,360,999
Gi0/3 1,100,110,310,330,340,350-351,360,999
Gi0/4 1,100,110,310,330,340,350-351,360,999
The core switch and the AS-02 switch ARE allowing this new VLAN into the management domain as shown here:
AS-02
Port Vlans allowed on trunk
Gi0/1 1-4094
Port Vlans allowed and active in management domain
Gi0/1 1,100,110,310,330,340,350-351,360,370
The AS-01 switch does NOT have any ports needing to access this VLAN 370 and I don't want it to. Are there commands I can input to allow this VLAN to be in themanagement domain on this middle AS-01 switch?
Thanks,
Dan
If you are not using VTP then make sure vlan 370 is configured on all switches and allowed across the proper trunks.
