[BTI] Upgrade considerations for SA-8xx from release 1.1 to later

0

0

Article ID: KB34728 KB Last Updated: 28 Sep 2019Version: 1.0
Summary:

This article will demonstrate how to configure in-band management when attempting to upgrade SA-8XX from R1.1.x to a newer release.

Symptoms:

SA-8XX is a one-step upgrade for any version, but in some cases you might lose the in-band management after upgrading from R1.1.x to later version.

Cause:

Prior to R1.2, SA-8XX allowed multiple VLAN-IP address bundling. Since R1.2, only one VLAN can bundle an IP address.

If you are using any VLAN besides VLAN 1 as an in-band management in R1.1.x, then after the upgrade, the IP address under your management interface will be deleted automatically. As a result, the management VLAN interface will be down and you will lose management connectivity.

Before Upgrade (R1.1.2)

interface vlan1
 
description vlan1
 
ip address 10.0.0.11/24
!

interface vlan4000
 
description vlan4000
 
ip address 192.168.1.1/24

After Upgrade (R2.2.1)

interface vlan1
 
description vlan1
 
ip address 10.0.0.11/24
!

interface vlan4000
 
description vlan4000​
Solution:

Go to delete the IP address under interface vlan 1 and save the configuration before you perform the upgrade.

BTI-SA-822(config)# interface vlan 1
BTI-SA-822(config-if)# no ip address ?
 
A.B.C.D    IP address
 
A.B.C.D/M  IP address (e.g. 10.0.0.1/8)
 
<cr>
BTI-SA-822(config-if)# no ip address
BTI-SA-822(config-if)# end
BTI-SA-822# write
Building configuration...
[OK]
BTI-SA-822#
