Upgrading switches using the
vsx update-software
command
Ensure that you have a scheduled maintenance window. There will be a disruption of service until the upgrade is complete and VSX is configured on the switches. It is advisable to have a support engineer from HPE available during this procedure.
- If you have enabled loop protect, enter the
show loop-protect
command for verifying that the action on loop detection has a value ofTX disable
on the VSX interface. If the setting has a different value, reset the value toTX disable
by entering theloop-protect action tx-disable
command:switch# configure terminal switch(config)# interface lag 2 multi-chassis switch(config-if)# loop-protect action tx-disable
- Back up the current software to the secondary image bank. Run the
show version
command. If theActive Image
isprimary
, copy the primary image to the secondary image bank:switch# copy primary secondary
If the current image bank is secondary, the current image, such as for 10.01, is already in the secondary bank.
Save a copy of the running configuration on both switches. One way to save a copy of the running configuration is to enter the following command:
switch# copy running-config sftp://<username>@<IP>/filename vrf mgmt
Check the status of the
show vsx brief
command and validate the ISL is in-sync and the keepalive is established.Check the output of the
show lacp interfaces multi-chassis
command and note which LACP interfaces are in a forwarding state of up.
