Virtual Switch Redundancy Protocol (VSRP)

Specifying no authentication for VSRP hello packets
The following configuration specifies no authentication as the preferred VSRP-aware security
method. In this case, the VSRP device will not accept incoming packets that have authentication
strings.
PowerConnect(config)#vlan 10
PowerConnect(config-vlan-10)#vsrp-aware vrid 2 no-auth
Syntax: vsrp-aware vrid <vrid number> no-auth
The following configuration specifies no authentication for VSRP hello packets received on ports
1/1, 1/2, 1/3, and 1/4 in VRID 4. For these ports, the VSRP device will not accept incoming
packets that have authentication strings.
PowerConnect(config)#vlan 10
PowerConnect(config-vlan-10)#vsrp-aware vrid 4 no-auth port-list ethe 1/1 to 1/4
Syntax: vsrp-aware vrid <vrid number> no-auth port-list <port range>
<vrid number> is a valid VRID (from 1 to 255).
no-auth specifies no authentication as the preferred VSRP-aware security method. The VSRP
device will not accept incoming packets that have authentication strings.
simple-text-auth <string> specifies the authentication string for accepting VSRP hello packets,
where <string> can be up to 8 characters.
port-list <port range> specifies the range of ports to include in the configuration.
Removing a port from the VRID VLAN
By default, all the ports on which you configure a VRID are interfaces for the VRID. You can remove
a port from the VRID while allowing it to remain in the VLAN.
Removing a port is useful in the following cases:
• There is no risk of a loop occurring, such as when the port is attached directly to an end host.
• You plan to use a port in an MRP ring.
To remove a port from a VRID, enter a command such as the following at the configuration level for
the VRID.
PowerConnect(config-vlan-200-vrid-1)#no include-port ethernet 1/2
Syntax: [no] include-port ethernet [<slotnum>/]<portnum>
The <slotnum> parameter is required on chassis devices.
The <portnum> parameter specifies the port you are removing from the VRID. The port remains in
the VLAN but its forwarding state is not controlled by VSRP. If you are configuring a chassis device,
specify the slot number as well as the port number (<slotnum>/<portnum>).
Configuring a VRID IP address
If you are configuring a Layer 3 Switch for VSRP, you can specify an IP address to back up. When
you specify an IP address, VSRP provides redundancy for the address. This is useful if you want to
back up the gateway address used by hosts attached to the VSRP Backups.
