Configuration Example to Create an IS-IS Adjacency between the VSP 8600 Series and Auto-sense Switches

Link Layer Discovery Protocol (LLDP) stations that connect to a local area network (LAN) advertise the station capabilities to each other, allowing the discovery of physical topology information for network management. When the system enables a switch as a Fabric Attach (FA) server in the Shortest Path Bridging (SPB) network, it receives LLDP messages from the FA Client and the FA Proxy devices using the LLDP Fabric Connect Type-Length-Value (TLV). For more information, see LLDP Fabric Connect TLV.

Following are the steps to create an Intermediate-System-to-Intermediate-System (IS-IS) adjacency between the VSP 8600 Series and Auto-sense switches.

On the VSP 8600 Series switch:

  1. Disable the High Availability-CPU mode.
  2. Enable the Shortest path bridging MAC (SPBM) mode.
  3. Create an SPBM instance.
  4. Create an SPBM B-VLAN.
  5. Configure the port that links to the Fabric Engine switch.

On the Fabric Engine switch:

  1. Enable the Shortest path bridging MAC (SPBM) mode.
  2. Enable Auto-sense on the port that links to the VSP 8600 Series switch.

Example

Create an IS-IS adjacency:

On the VSP 8600 Series switch:

enable
configure terminal
no boot config flags ha-cpu
boot config flags spbm-config-mode
spbm 
router isis
spbm 1
spbm 1 b-vid 100,101 primary 100
spbm 1 nick-name 1.44.66
manual-area c1
exit
vlan create 100 type spbm-bvlan
vlan create 101 type spbm-bvlan
vlan members remove 1 1/3
interface gigabitEthernet 1/3
isis
isis spbm 1 
isis enable
router isis enable

On the Fabric Engine switch:

enable
configure terminal
boot config flags spbm-config-mode
interface gigabitEthernet 1/3
auto-sense enable
