5130 Switches: Issue adding vlan to 1 switch of 2 switches trunked (Aggregated BAGG) together

[Andy5]

Hello..  I have two 5130 switches Trunked (Aggregated) together.

Link Aggregation group: BAGG2
Aggregation mode: Dynamic
Member Ports:
GE1/0/3
GE1/0/4
GE1/0/5
GE1/0/6

This (BAGG2) is the same on both switches for the ports. They differ when it comes to the vlans allowed.

For Switch one:

interface Bridge-Aggregation2
port link-type trunk
undo port trunk permit vlan 1
port trunk permit vlan 10 20 30 99 997
port trunk pvid vlan 20
link-aggregation mode dynamic

For Switch 2:

interface Bridge-Aggregation2
port link-type trunk
undo port trunk permit vlan 1
port trunk permit vlan 10 20 30 997
port trunk pvid vlan 20
link-aggregation mode dynamic

On switch the member interfaces are set up as follows:

interface GigabitEthernet1/0/3
port link-type trunk
undo port trunk permit vlan 1
port trunk permit vlan 10 20 30 99 997
port trunk pvid vlan 20
port link-aggregation group 2
#
interface GigabitEthernet1/0/4
port link-type trunk
undo port trunk permit vlan 1
port trunk permit vlan 10 20 30 99 997
port trunk pvid vlan 20
port link-aggregation group 2
#
interface GigabitEthernet1/0/5
port link-type trunk
undo port trunk permit vlan 1
port trunk permit vlan 10 20 30 99 997
port trunk pvid vlan 20
port link-aggregation group 2
#
interface GigabitEthernet1/0/6
port link-type trunk
undo port trunk permit vlan 1
port trunk permit vlan 10 20 30 99 997
port trunk pvid vlan 20
port link-aggregation group 2

On switch two the member interfaces are set up as:

interface GigabitEthernet1/0/3
port link-type trunk
undo port trunk permit vlan 1
port trunk permit vlan 10 20 30 997
port trunk pvid vlan 20
port link-aggregation group 2
#
interface GigabitEthernet1/0/4
port link-type trunk
undo port trunk permit vlan 1
port trunk permit vlan 10 20 30 997
port trunk pvid vlan 20
port link-aggregation group 2
#
interface GigabitEthernet1/0/5
port link-type trunk
undo port trunk permit vlan 1
port trunk permit vlan 10 20 30 997
port trunk pvid vlan 20
port link-aggregation group 2
#
interface GigabitEthernet1/0/6
port link-type trunk
undo port trunk permit vlan 1
port trunk permit vlan 10 20 30 997
port trunk pvid vlan 20
port link-aggregation group 2

As you can see the permitted vlan 99 is missing on switch 2. What I would like to do is add vlan 99 to the list of permitted vlans so that it matches switch one.

VLAN 99 is a working VLAN on switch 2 so it's not that it's completely missing from switch 2.

I try and accomplish by going to VLAN on the web console, then VLAN 99,  then just adding interfaces 3-6 to the tagged port list. When I hit apply it seems to bring down the trunked (aggregated ?) ports between the two switches.

I'm hoping I can get the proper steps of adding VLAN 99 to switch 2 so it will match switch 1 (web console or command prompt).

Thank you...

command is :

int br2
port trunk permit vlan 99

Provided that the vlan is added to the switch, you should be able to add
it. I would also try command line as opposed to web interface:

Check vlans on the switch:

display vlan

Then add the vlan via BAGG2:

Interface Bridge-Aggregation2
port trunk permit vlan 99

This should apply the vlan to the member ports.

Good luck!

By using the "port trunk permit vlan 99" command will it add vlan 99 to the currently added/allowed vlans on the switch or will it replace the currently added/allowed vlans via BAGG2?

Thank you...

[cgu]

It will be added.

[FalconSez]

cgu is correct.

Only was to remove vlans is via "undo" command....

Thank you for all the great help on this issue. One last thing, if I should need to undo any of the changes I make what command/s would I need to enter.
