Configure Esrp Mode - Extreme Networks ExtremeWare XOS Command Reference Manual

ExtremeWare XOS 11.5 supports only the Summit X450 family of switches and the BlackDiamond 8800 series switch.
ESRP Commands

configure esrp mode

configure esrp mode [extended | standard]
Description
Configures the mode of operation for ESRP on the switch.
Syntax Description
extended
standard
Default
The default mode is extended.
Usage Guidelines
Use standard ESRP if your network contains a combination of switches running ExtremeWare XOS and
ExtremeWare participating in ESRP. With standard ESRP, the switches running ExtremeWare XOS are
backward compatible with the switches running ExtremeWare.
Use extended ESRP if your network contains switches running only ExtremeWare XOS; this is the
default.
If your network has switches currently running ExtremeWare, and you add a BlackDiamond 10808
switch, a BlackDiamond 8800 series switch, a BlackDiamond 12804 switch, or a Summit X450 family
switch running ExtremeWare XOS, select standard ESRP. By selecting standard, the switch running
ExtremeWare XOS is backward compatible with the ExtremeWare implementation of ESRP.
If you use the default mode—extended—and your ESRP domain contains a switch running
ExtremeWare XOS that detects a neighbor switch running ExtremeWare, the mode automatically
changes to standard for that domain. This action causes the switch to enter the neutral state and re-elect
the ESRP master. Since you are using the default mode of operation, and the switch running
ExtremeWare XOS detected a neighbor switch running ExtremeWare, the ExtremeWare XOS switch
toggles to standard mode although the configured mode of operation remains as extended.
Example
The following command configures ESRP to run in standard mode:
configure esrp mode standard
1268
Specifies ESRP extended mode. This mode is compatible with devices running
ExtremeWare XOS and is not backward compatible with devices running
ExtremeWare.
Specifies ESRP standard mode. This mode is backward compatible with
devices running ExtremeWare.
