(HP_Switch_name#) distributed-trunking

peer-keepalive destination 20.0.0.2

3. Ping the keepalive destination address to make sure that there is connectivity between the two

DT switches (keepalive VLANs.)

4. Enable the ISC link on both switches, and then execute write memory. Assume a2 is

configured as switch-interconnect.

(HP_Switch_name#) int a2 enable

(HP_Switch_name#) write mem

When updating software from a software version that does support shared DT keepalive (K.15.03,

K.15.04) to a version that supports dedicated point-to-point keepalive (K.15.05), use the following

procedure:

1. Disable the ISC interface and undo the keepalive configuration on both switches. Ignore the

warning message that is displayed by the keepalive command while undoing the configuration.

Upgrade the software. Assume a2 is configured as switch-interconnect.

(HP_Switch_name#) int a2 disable

(HP_Switch_name#) no distributed-trunking

peer-keepalive vlan

(HP_Switch_name#) write mem

2. At switch bootup, create a dedicated VLAN for keepalive and assign only the keepalive link

port as a member port of the VLAN. Configure the keepalive destination IP address.

(HP_Switch_name#) vlan 10 (dedicated point-to-point VLAN interface)

HP Switch(vlan-10)#

HP Switch(vlan-10)# untagged b2 (keepalive link port)

HP Switch(vlan-10)# ip address 10.0.0.1/24

HP Switch(vlan-10)# exit

(HP_Switch_name#) distributed-trunking

peer-keepalive vlan 10

(HP_Switch_name#) distributed-trunking

peer-keepalive destination 10.0.0.2

3. Ping the keepalive destination address to make sure that there is connectivity between the two

DT switches (keepalive VLANs.)

4. Enable the ISC link on both switches, and then execute write memory. Assume a2 is

configured as switch-interconnect.
