Configuring optional SPBM parameters

Use the following procedure to configure optional SPBM parameters.

Procedure

  1. Enter Global Configuration mode:

    enable

    configure terminal

  2. Configure the SPBM ethertype:

    spbm ethertype {0x8100 | 0x88a8}

  3. Configure the optional link-state database (LSDB) trap global parameter. To configure this parameter, you must globally disable IS-IS on the switch:
    1. Disable IS-IS on the switch:

      no router isis enable

    2. Enter IS-IS Router Configuration mode:

      router isis

    3. Enable a trap when the SPBM LSDB changes:

      spbm <1–100> lsdb-trap enable

    4. Enable IS-IS on the switch:

      router isis enable

    5. Exit IS-IS Router Configuration mode:

      exit

  4. Configure the optional SPBM interface parameters. To configure these parameters, you must disable IS-IS on the interface:
    1. Specify an SPBM interface to configure:

      interface {GigabitEthernet {slot/port[/sub-port][-slot/port[/sub-port]][,...]} | mlt <mltid> }

    2. Disable IS-IS on the interface:

      no isis enable

    3. Configure SPBM instance interface-type on IS-IS interface. SPBM supports only pt-pt:

      isis spbm <1–100> interface-type {broadcast|pt-pt}

    4. Configure the IS-IS Interface level 1 metric:

      isis spbm <1–100> l1-metric <1–16777215>

    5. Enable IS-IS on the switch:

      isis enable

Example

Switch> enable

Switch# configure terminal

Switch(config)# spbm ethertype 0x8100

Switch(config-isis)# no router isis enable

Switch(config)# router isis

Switch(config-isis)# spbm 1 lsdb-trap enable

Switch(config-isis)# router isis enable

Switch(config-isis)# exit

Switch(config)# interface gigabitethernet 1/7

Switch(config-if)# no isis enable

Switch(config-if)# isis spbm 1 interface-type pt-pt

Switch(config-if)# isis spbm 1 l1–metric 500

Switch(config-if)# isis enable

Variable definitions

The following table defines parameters for the spbm command.

Variable

Value

ethertype {0x8100 | 0x88a8}

Configures the SPBM ethertype. The default value is 0x8100.

<1–100> lsdb-trap enable

Configures whether to enable or disable a trap when the SPBM LSDB changes.

The default is disabled. Use the no or default options to disable LSDB traps.

The following table defines parameters for the isis spbm command.

Variable

Value

<1–100> interface-type {broadcast|pt-pt}

Configures the SPBM instance interface-type on the IS-IS interface located on the specified port or MLT. SPBM only supports the point-to-point (pt-pt) interface type.

The default is pt-pt. Use the no or default options to set this parameter to the default value of pt-pt.

<1–100> l1–metric <1–16777215>

Configures the IS-IS interface level 1 metric on the specified port or MLT. The default value is 10.

Use the no or default options to set this parameter to the default.
