Nexus7010(config-if)# switchport

Nexus7010(config-if)# switchport mode trunk

Nexus7010(config-if)# switchport trunk allowed vlan 2001-2003

Nexus7010(config-if)# no shutdown

Nexus7010(config-if)# end

Note that Cisco Nexus 7000 switches require an explicit “no shutdown” command to

enable an interface.

Cisco Catalyst 3850:

1. Cisco Catalyst switches do not require any RTG-specific configuration. Simply define

VLANs; disable spanning tree on those VLANs; and assign switch ports to be trunk-

mode members of those VLANs:

Cat3850# configure terminal

Cat3850(config)# vlan 2001-2003

Cat3850(config-vlan)# exit

Cat3850(config)# no spanning-tree vlan 2001-2003

Cat3850(config)# interface TenGigabitEthernet1/1/3

Cat3850(config-if)# description RTG to Juniper VCF xe-1/0/10

Cat3850(config-if)# switchport

Cat3850(config-if)# switchport mode trunk

Cat3850(config-if)# switchport trunk allowed vlan 2001-2003

Cat3850(config)# interface TenGigabitEthernet1/1/4

Cat3850(config-if)# description RTG to Nexus 7010 e3/7

Cat3850(config-if)# switchport

Cat3850(config-if)# switchport mode trunk

Cat3850(config-if)# switchport trunk allowed vlan 2001-2003

Cat3850(config-if)# end

Validation!

The show redundant-trunk-group command indicates the current RTG state.

This example is from the Juniper Virtual Chassis Fabric:

admin@VCF# run show redundant-trunk-group group rtg0

Interface State Bandwidth Time of last flap

count

xe-1/0/2.0 Up/Pri/Act 10 Gbps Never

xe-1/0/10.0 Up 10 Gbps 2014-04-18 01:38:23 (00:01:55 ago)

Note that interface xe-1/0/2.0 is the primary path. After offering traffic from Spirent

TestCenter, the packet counters for interfaces xe-1/0/2.0 and xe-1/0/10.0 will indicate that

the switch forwarded all traffic to interface xe-1/0/2.0, the primary path in the RTG.

To verify correct operation of RTG redundancy, disable the primary path:

1 2 ... 48 49 50 51 52 53 54 55 56 57 58 ... 82 83
