Configuration Example

The following example show how to set up a controlling bridge (CB) with two attached bridge port extenders (BPEs) with the topology shown in CB with two BPEs Topology.

CB with two BPEs Topology

On the CB, enable VPEX mode:

X670G2-48x-4q.1 # enable vpex
X670G2-48x-4q.1 # reboot
Are you sure you want to reboot the switch? (y/N) Yes
Slot-1 VPEX X670G2-48x-4q.1 #

Note

After reboot, command prompt changes to show that you are in VPEX mode.

Create LAGs between CB and BPEs:

Slot-1 VPEX X670G2-48x-4q.1 # enable sharing 1:10 group 1:10-1:11
Slot-1 VPEX X670G2-48x-4q.2 # enable sharing 1:20 group 1:20-1:21

Configure slot identifiers associated with BPEs:

Slot-1 VPEX X670G2-48x-4q.1 # configure vpex port 1:10 slot 33
WARNING: This command will remove VLAN membership from the
         port 1:10.
         Do you want to continue? (y/N)Yes

Slot-1 VPEX X670G2-48x-4q.2 # configure vpex port 1:20 slot 34
WARNING: This command will remove VLAN membership from the
         port 1:20.
         Do you want to continue? (y/N)Yes

Slot-1 VPEX X670G2-48x-4q.3 # show slot
Slots    Type                 Configured           State       Ports   Flags
--------------------------------------------------------------------------------
Slot-1   X670G2-48x-4q        X670G2-48x-4q        Operational   64    M
Slot-33  V400-48p-10GE4                            Operational   52
Slot-34  V400-48p-10GE4                            Operational   52
Flags : M - Backplane link to Master is Active
        B - Backplane link to Backup is also Active
        D - Slot Disabled
        I - Insufficient Power (refer to "show power budget")

Slot-1 VPEX X670G2-48x-4q.9 # show vpex
Virtual Port Extender: Enabled
Cascade
Port     Slot
=============
1:10     33
1:20     34

Note

Observe that the show slot command shows the CB as slot 1 with the two BPEs as slots 33 and 34.

Note

Observe that the show vpex command shows that ports 1:10 and 1:20 are the cascade ports connecting to the BPEs.

Apply Layer 2 configuration:

Slot-1 VPEX X670G2-48x-4q.1 # configure vlan Default delete port all
Slot-1 VPEX X670G2-48x-4q.2 # create vlan v100 tag 100
Slot-1 VPEX X670G2-48x-4q.3 # configure vlan v100 add port 33:1-2, 34:1-2, 1:7 tagged

If required, you can use standard show commands to troubleshoot the network from the CB using the counters:

Slot-1 VPEX X670G2-48x-4q.3 # show port 33:1-2, 34:1-2, 1:7 statistics no-refresh
