Default values Auto
15.3.6 Set Ring Coupling Uplink Priority
Syntax [no] priority <1..65535> [adjust <DELTA>]
Context Ring Coupling Uplink Configuration context
Usage Configure uplink priority, and optionally enable sticky uplink election by
setting adjust value.
❼ Use ”priority VALUE” to set priority value. A lower value increases
the chance for this uplink to be elected as active uplink (lower is better).
With equal path-cost (
section 15.3.5 ), an uplink with ”priority 100”
is preferred as uplink over an uplink with ”priority 110”.
❼ Use the optional ”adjust DELTA” setting to improve its priority (i.e.,
lower its priority with the specified ”DELTA”) once the uplink is elected
as active uplink. This gives a sticky uplink behaviour where shifting
active uplink will be less common.
Consider the following example with uplink A (”priority 100”), uplink
B (”priority 110 adjust 20”), and uplink C (”priority 120 adjust
40”), and where uplink A came up first and is the active uplink. If uplink
A goes down, uplink B takes over as it has lower priority than uplink
C (110 < 120). Uplink B will then apply its adjustment and announce
priority to 90 (110 − 20) in its hello messages. Uplink B will stay as
active uplink even if uplink A comes up again (90 < 100).
”show priority” will show the configured uplink priority.
Default values priority 128 (no adjustment)
15.3.7 Managing Multi-Link Dual-Homing
Syntax [no] dual-homing [ID]
Context Global Configuration context
Usage Use ”dual-homing ID” to enter Dual-Homing Configuration context of
the given Dual-Homing instance ID. Default instance ID is ”1”, thus com-
mand ”dual-homing” will enter the context of dual-homing instance 1.
