Configuring ESRP-Aware Switches

For an Extreme Networks switch to be ESRP-aware, you must create an ESRP domain on the aware switch, add a master VLAN to that ESRP domain, add a member VLAN to that ESRP domain if configured, 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.
• If configured, the member VLAN name and IP address must be identical on all switches (ESRP-enabled and ESRP-aware) participating in ESRP for that particular domain.
• The domain ID must be identical on all switches (ESRP-enabled or ESRP-aware) participating in ESRP for that particular domain.
• If you have an untagged master VLAN, you must specify an ESRP domain ID.
• If you have a tagged master VLAN, ESRP uses the 802.1Q tag (VLANid) of the master VLAN for the ESRP domain ID. If you do not use the VLANid as the domain ID, you must specify a different domain ID.

Note

Before you begin, make a note of the ESRP domain parameters on the ESRP-enabled switch. That way you can easily refer to your notes while creating the ESRP domain on the ESRP-aware switch.
