Esrp Modes Of Operation - 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
Licensing
You must have an Advanced Edge, Core, or Advanced Core license to configure and use all of the ESRP
features described in this chapter.
If you have an Edge license, you can configure your Extreme Networks switch to be ESRP-aware. ESRP-
aware switches do not actively participate in ESRP; however, when connected to a network with ESRP-
enabled switches, the ESRP-aware switches reliably perform failover and failback scenarios in the
prescribed recovery times.
The BlackDiamond 10808 switch with an MSM-1 module or an MSM1-XL module ships with a Core or
Advanced Core license, respectively.
The BlackDiamond 12804 switch with an MSM-5 module or an MSM-5R module ships with a Core
license.
The BlackDiamond 8800 series switch (formerly known as Aspen), Summit X450 series switch, and
Summit X450a series switch ship with an Advanced Edge license.
The Summit X450e series switch ships with an Edge license, which only supports ESRP-aware. You can,
however, upgrade to an Advanced Edge license that supports ESRP.
For more information about software licensing, including how to obtain and upgrade your license, see
Chapter 1, "ExtremeWare XOS Overview,"

ESRP Modes of Operation

ExtremeWare XOS has two modes of ESRP operation: standard and extended. Select standard if your
network contains some switches running ExtremeWare, others running ExtremeWare XOS, and a
combination of those switches participating in ESRP. Standard ESRP is backward compatible with and
supports the ESRP functionality of ExtremeWare.
Select extended ESRP if your network contains switches running only ExtremeWare XOS. Extended
mode ESRP supports and is compatible with switches running ExtremeWare XOS. By default,
ExtremeWare XOS operates in extended mode.
ESRP-Aware Switches
Extreme Networks switches that are not actively participating in ESRP but are connected on a network
that has other Extreme Networks switches running ESRP are ESRP-aware. When ESRP-aware switches
are attached to ESRP-enabled switches, the ESRP-aware switches reliably perform failover and failback
scenarios in the prescribed recovery times. For an Extreme Networks switch to be ESRP-aware, you
must create an ESRP domain on the aware switch (however, you do not enable the ESRP domain), add
a master VLAN to that ESRP domain, and configure a domain ID, if necessary.
To participate as an ESRP-aware switch, the following must be true:
The ESRP domain name must identical on all switches (ESRP-enabled and ESRP-aware) participating
●
in ESRP for that particular domain.
The master VLAN name and IP address must be identical on all switches (ESRP-enabled and ESRP-
●
aware) participating in ESRP for that particular domain.
