dump  Displays information for all multicast groups learned by the switch. 
 
VRRP information 
Virtual Router Redundancy Protocol (VRRP) support on GbE2c provides redundancy between routers in a LAN. This is 
accomplished by configuring the same virtual router IP address and ID number on each participating VRRP-capable 
routing device. One of the virtual routers is then elected as the master, based on a number of priority criteria, and 
assumes control of the shared virtual router IP address. If the master fails, one of the backup virtual routers will assume 
routing authority and take control of the virtual router IP address. 
 
NOTE:  VRRP commands are available only on the GbE2c Layer 2/3 Ethernet Blade Switch.  
 
Command: /info/l3/vrrp 
VRRP information: 
1: vrid 2, 205.178.18.210, if 1, renter, prio 100, master, server 
2: vrid 1, 205.178.18.202, if 1, renter, prio 100, backup 
3: vrid 3, 205.178.18.204, if 1, renter, prio 100, master, proxy 
 
When virtual routers are configured, you can view the status of each virtual router using this command. VRRP 
information includes: 
•  Virtual router number 
•  Virtual router ID and IP address 
•  Interface number 
•  Ownership status 
•  owner identifies the preferred master virtual router. A virtual router is the owner when the IP address of the 
virtual router and its IP interface are the same. 
•  renter identifies virtual routers which are not owned by this device 
•  Priority value. During the election process, the virtual router with the highest priority becomes master. 
•  Activity status 
•  master identifies the elected master virtual router. 
•  backup identifies that the virtual router is in backup mode.
