Juniper Networks/Cisco Systems Switch Interoperability Cookbook

! ! !

All devices are configured as switches and all inter-switch links act as VLAN trunks.

However, even without VLAN configuration CDP traffic will be forwarded just as in this

example. Figure 1 shows the topology for CDP passthrough.

In this example, the inter-switch ports use link aggregation and VLAN trunking. Both

steps are optional; if desired, physical switch ports can instead be configured for Ethernet

switching.

These steps define two VLANs; again, this is optional:

admin@EX9208> configure

admin@EX9208# set vlans v2001 vlan-id 2001

admin@EX9208# set vlans v2002 vlan-id 2002

These steps create link aggregation groups ae1 to the Cisco Catalyst 3850 and ae2 to the

Cisco Nexus 7010:

admin@EX9208# set interfaces ae1 aggregated-ether-options lacp active

admin@EX9208# set interfaces ae1 description "linkagg to 3850"

admin@EX9208# set interfaces ae2 aggregated-ether-options lacp active

admin@EX9208# set interfaces ae2 description “linkagg to 7010"

These steps configure the newly created ae interfaces as Ethernet switching and VLAN

trunk ports:

admin@EX9208# set interfaces ae1 unit 0 family ethernet-switching

interface-mode trunk

admin@EX9208# set interfaces ae1 unit 0 family ethernet-switching vlan

members v2001

admin@EX9208# set interfaces ae1 unit 0 family ethernet-switching vlan

members v2002
