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.
The command to clear a bonding port is set bonding port <port range> disable
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.
  • If configuring more than multiple bonded systems be sure that the Bonding MAC addresses are unique for each system
