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 (Virtual LAN) 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.
 
    
      To configure an ESRP-aware switch:
     
    
      - 
        Create an ESRP domain using the command:  
        
        
      
- 
        Add a master VLAN to your ESRP domain using the command:  
        
      
- 
        If configured, add the member VLANs to your ESRP domain
          using the command: 
        
      
- 
        If necessary, configure a domain ID for the ESRP domain
          using the command:
