Simple Ring Configuration Example

The following example shows how to set up a simple Extended Edge Switching ring configuration (see CB with Simple Ring Topology).

CB with Simple Ring Topology

Attach BPEs.

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.

Configure slot identifiers associated with the first-tier BPEs in cascades 1 and 2:

Slot-1 VPEX X670G2-48x-4q.1 # configure vpex port 1:10 slot 110
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 120
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

        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     110
1:20     120

Note

Observe that the show slot command shows the CB as slot 1 with the two BPEs as slots 110 and 120.

Note

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

Configure slot identifiers associated with the second-tier BPEs in cascades 1 and 2:

Slot-1 VPEX X670G2-48x-4q.1 # configure vpex port 110:49 slot 130
WARNING: This command will remove VLAN membership from the
         port 110:49.
         Do you want to continue? (y/N)Yes

Slot-1 VPEX X670G2-48x-4q.2 # configure vpex port 120:49 slot 140
WARNING: This command will remove VLAN membership from the
         port 120:49.
         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-110 V400-48p-10GE4                            Operational   52
Slot-120 V400-48p-10GE4                            Operational   52
Slot-130 V400-48p-10GE4                            Operational   52
Slot-140 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

=============
1:10     110
1:20     120
110:49   130
120:49   140

Note

Observe that the show slot command shows the CB as slot 1 with the four BPEs as slots 110, 120, 130, and 140.

Note

Observe that the show vpex command shows that ports 1:10, 1:20, 110:49, and 120:49 are the cascade ports connecting to the BPEs.

Connect the end of cascade 1 to cascade 2 to form the ring:

<Noti:VPEX.Ring.Dtect> Slot-1: Ring detected between ports 140:49 and 130:49
