Configuring VSB

This section provides a table of VSB default values and a procedure for configuring a VSB system. The following table lists VSB default values.

Default VSB Parameters

Parameter	Description	Default Value
Chassis ID	Identifies a VSB system chassis.	None.
System ID	Identifies a VSB system made up of two VSB chassis.	None.
LFR priority	Used to determine the physical chassis to be put in dormant state should all VSB interconnect links go down.	10 times the chassis ID.
LFR state	Specifies whether LFR is globally enabled or disabled on the physical chassis.	Disabled.
MAC address	VSB system MAC address	An internal MAC address associated with VSB chassis 1.
outport local preference	LACP VSB only feature that determines the likelihood of a packet that ingresses the local chassis egressing the VSB system using a local chassis LAG port.	None.
VSB state	Specifies whether VSB is globally enabled or disabled on the physical chassis.	Disabled.

The following procedure describes VSB configuration on the Extreme Networks S- and K-Series devices. All commands used to configure VSB can be entered in any command mode.

Configuring VSB

Step	Task	Command(s)
1	On each chassis, configure each chassis‘ VSB chassis ID and the ID of the VSB system the two chassis belong to. Optionally: Configure an encrypted secret used on the VSB links Administratively change the LFR priority for the physical chassis	set bonding chassis chassis-id {system-id system-id | secret secret | lfr-priority priority}
2	Validate VSB feature entitlement by activating licenses on any S150 or S130 modules (S155 modules support VSB by default). Enclose the license key in double quotes (“”).	set license vsb license-key
3	Optionally change the VSB system MAC address from the default value.	set bonding mac mac-address
4	On the S-Series platform, set the VSB interconnect port bonding mode.	set bonding mode {hard | soft}
5	Enable bonding on the: 10GbE ports to be used as VSB interconnect ports. 1GbE ports to be used as LFR monitor ports	set bonding port [port-string] enable
6	Globally enable LFR on the physical chassis.	set bonding lfr enable
7	Globally enable the VSB system.	set bonding enable
8	Optionally configure LACP outport local preference on the VSB system.	set lacp outportLocalPreference {none | weak | strong | all-local}
9	Optionally configure the VSB system for High Availability firmware upgrades	See High Availability Firmware Upgrade.
