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



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

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


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.


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

interface vlan4000
description vlan4000
ip address

After Upgrade (R2.2.1)

interface vlan1
description vlan1
ip address

interface vlan4000
description vlan4000​

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.
BTI-SA-822(config-if)# no ip address
BTI-SA-822(config-if)# end
BTI-SA-822# write
