TitleHow to configure Virtual Switch Bonding (VSB) on S-Series or K-Series
Objective
How to configure Virtual Switch Bonding (VSB) on S-Series or K-Series
Environment
  • S-Series
  • K-Series
  • S-Series firmware: Minimum version of 07.61.01.0005
  • K-Series firmware: Minimum version of 08.21.02.0001
Procedure
  • IMPORTANT NOTE:  Setting up Bonding will wipe all previous configuration on both chassis
  • Enclose the license key in double quotes (“”).
  • Basic configuration for bonding on S-Series, noting that the system-id must match on all chassis:
S-Series Switch#1:
set license vsb "<LICENSE_KEY>" chassis 1
set bonding chassis 1 system-id 1
set bonding port ge.1.1 enable
set bonding port tg.1.101 enable
set bonding port tg.1.102 enable
set bonding lfr enable
set bonding mac 00-01-02-00-01-01
set bonding enable

S-Series Switch#2:
set license vsb "<LICENSE_KEY>" chassis 2
set bonding chassis 2 system-id 1
set bonding port ge.1.1 enable
set bonding port tg.1.101 enable
set bonding port tg.1.102 enable
set bonding lfr enable
set bonding mac 00-01-02-00-01-01
set bonding enable
  • The tg.1.101 and tg.1.102 ports are used for 10gb bonded ports, and the ge.1.1 port is used for the link failure response (LFR).
  • Configuring the system MAC address is recommended. Unique mac addresses are supported and by default is based off of chassis-1 MAC address in the bonded setup, but this requires a master election process to take place which requires an additional reboot of the chassis when joined together. The chassis MAC cannot be configured if bonding is enabled.
Additional notes
  • LACP Outport local preference is a VSB only feature that increases the likelihood that the packet flow will egress the system using a LAG port on the local chassis and not utilize the VSB interconnect link
  • Bonding ports are required to be 10GB, while LFR ports are required to be 1GB
  • The Link Failure Response (LFR) protocol provides for the configuration of one or more monitor links.
  • Depending on hardware class, a license may be required.
  • The VSB license is not required when the HW VSB ports are installed.
  • LFR priority can be used to determine which chassis is taken out of operation should all VSB interconnect links go down.  The command to do this is "set bonding chassis <chassis-id> lfr-priority <1-255>"
  • Setting the LFR priority to the same value for both chassis in the VSB system is not allowed.
  • The physical chassis with highest LFR priority in the bonded pair will remain active while placing the chassis with the lower priority into a dormant state.
  • The LFR protocol must be enabled on each VSB chassis in the VSB system for LFR monitoring to occur.
