DXS-3350SR Gigabit Layer 3 Switch
Description
Enter the name of a previously configured IP interface to create a VRRP entry for.
This IP interface must be assigned to a VLAN on the Switch.
Enter a value between 1 and 255 to uniquely identify this VRRP group on the Switch.
All routers participating in this group must be assigned the same VRID value. This
value MUST be different from other VRRP groups set on the Switch.
Enter the virtual IP address that will be assigned to the VRRP entry. This IP address
is also the default gateway that will be statically assigned to end hosts and must be
set for all routers that participate in this group.
Used to enable (Up) and disable (Down) the VRRP IP interface on the Switch.
Enter a value between 1 and 254 to indicate the router priority. The VRRP Priority
value may determine if a higher priority VRRP router overrides a lower priority VRRP
router. A higher priority will increase the probability that this router will become the
Master router of the group. A lower priority will increase the probability that this router
will become the backup router. VRRP routers that are assigned the same priority
value will elect the highest physical IP address as the Master router. The default value
is 100. (The value of 255 is reserved for the router that owns the IP address
associated with the virtual router and is therefore set automatically.)
Enter a time interval value, in seconds, for sending VRRP message packets. This
value must be consistent with all routers participating within the same VRRP group
and is used to troubleshoot incorrectly configured routers. The default is 1 second.
This entry will determine the behavior of backup routers within the VRRP group by
controlling whether a higher priority backup router will preempt a lower priority Master
router. A True entry, along with having the backup router's priority set higher than the
masters priority, will set the backup router as the Master router. A False entry will
disable the backup router from becoming the Master router. This setting must be
consistent with all routers participating within the same VRRP group. The default
setting is True.
Enter the IP address of the physical device that will provide the most direct route to
the Internet or other critical network connections from this virtual router. This must be
a real IP address of a real device on the network. If the connection from the virtual
router to this IP address fails, a new Master will be elected from the backup routers
participating in the VRRP group. If the connection to the backup fails, this backup
router cannot assume the Master router role. Different critical IP addresses may be
assigned to different routers participating in the VRRP group, and can therefore define
multiple routes to the Internet or other critical network connections.
Use the pull-down menu to enable or disable the Critical IP address entered above.
Specifies the type of authentication used. The Auth. Type must be consistent with all
routers participating within the VRRP group. The choices are:
None - Selecting this parameter indicates that VRRP protocol exchanges will not be
authenticated.
Simple - Selecting this parameter will require the user to set a simple password in the
Auth. Data field for comparing VRRP message packets received by a router. If the two
passwords are not exactly the same, the packet will be dropped.
IP - Selecting this parameter will require the user to set a MD5 message digest for
authentication in comparing VRRP messages received by the router. If the two values
are inconsistent, the packet will be dropped.
This field is only valid if the user selects Simple or IP in the Auth. Type field. Simple
will require the user to enter an alphanumeric string of no more than 8 characters to
identify VRRP packets received by a router. IP will require the user to enter a MD5
message digest for authentication in comparing VRRP messages received by the
router
