The example in STP Redundancy Configuration Example configures a VLAN (Virtual LAN) translation network with redundant paths protected by STP (Spanning Tree Protocol).
Parallel paths exist from the member VLAN portion of the network to the translation switch. STP ensures that the main path for this traffic is active and the secondary path is blocked. If a failure occurs in the main path, the secondary paths are enabled.
The following configuration commands create the member VLANs and enable STP on SW1:
create vlan v101 configure v101 tag 101 configure v101 add ports 1:1 tagged configure v101 add ports 1:3 tagged configure v101 add ports 1:4 tagged create vlan v102 configure v102 tag 102 configure v102 add ports 1:2 tagged configure v102 add ports 1:3 tagged configure v102 add ports 1:4 tagged create vlan v103 configure v103 tag 103 configure v103 add ports 1:3 tagged configure v103 add ports 1:4 tagged create vlan v104 configure v104 tag 104 configure v104 add ports 1:3 tagged configure v104 add ports 1:4 tagged create stpd stp1 configure stp1 tag 101 configure stp1 add vlan v101 configure stp1 add vlan v102 configure stp1 add vlan v103 configure stp1 add vlan v104 enable stpd stp1
These configuration commands create the member VLANs and enable STP on SW2:
create vlan v103 configure v103 tag 103 configure v103 add ports 1:1 tagged configure v103 add ports 1:3 tagged configure v103 add ports 1:4 tagged create vlan v104 configure v104 tag 104 configure v104 add ports 1:2 tagged configure v104 add ports 1:3 tagged configure v104 add ports 1:4 tagged create vlan v101 configure v101 tag 101 configure v101 add ports 1:3 tagged configure v101 add ports 1:4 tagged create vlan v102 configure v102 tag 102 configure v102 add ports 1:3 tagged configure v102 add ports 1:4 tagged create stpd stp1 configure stp1 tag 101 configure stp1 add vlan v101 configure stp1 add vlan v102 configure stp1 add vlan v103 configure stp1 add vlan v104 enable stpd stp1
This set of configuration commands creates the member VLANs and enables STP on SW3:
create vlan v101 configure v101 tag 101 configure v101 add ports 1:3 tagged configure v101 add ports 1:4 tagged create vlan v102 configure v102 tag 102 configure v102 add ports 1:3 tagged configure v102 add ports 1:4 tagged create vlan v103 configure v103 tag 103 configure v103 add ports 1:3 tagged configure v103 add ports 1:4 tagged create vlan v104 configure v104 tag 104 configure v104 add ports 1:3 tagged configure v104 add ports 1:4 tagged create stpd stp1 configure stp1 tag 101 configure stp1 add vlan v101 configure stp1 add vlan v102 configure stp1 add vlan v103 configure stp1 add vlan v104 enable stpd stp1
The final set of configuration commands creates the translation VLAN and enables VLAN translation on SW3:
create vlan v1000 configure v1000 tag 1000 configure v1000 add ports 2:1 tagged configure v1000 vlan-translation add member-vlan v101 configure v1000 vlan-translation add member-vlan v102 configure v1000 vlan-translation add member-vlan v103 configure v1000 vlan-translation add member-vlan v104
The following configuration commands create the translation VLAN and enable VLAN translation on VLANs that have overlapping ports:
configure v1000 vlan-translation add member-vlan v102 loopback-port 1:22 configure v1000 vlan-translation add member-vlan v103 loopback-port 1:23 configure v1000 vlan-translation add member-vlan v104 loopback-port 1:24
