Chapter 7 Configuring the Cisco IOS In-Service Software Upgrade Process
Performing the ISSU Process
Upgrading ISSU to Cisco IOS XE 3.4.0SG/15.1(2)SG from a Prior Release
Because images prior to Cisco IOS XE 3.4.0SG/15.1(2)SG use the earlier CLI format and Cisco IOS XE
3.4.0SG and 15.1(2)SG images use a newer CLI format, your upgrade consists of the following:
•
Upgrading the image on your switch to Cisco IOS XE 3.4.0SG/15.1(2)SG.
•
Upgrading mgmtVrf from the earlier CLI format to the later format, removing any IPv6 addresses
on the interface.
•
Enabling IPv6 address family under mgmtVrf, and reconfigure IPv6 addresses on fa1.
A configuration like the following should exist on pre-Cisco IOS XE 3.4.0SG/15.1(2)SG image:
ip vrf mgmtVrf
!
interface FastEthernet1
ip vrf forwarding mgmtVrf
ip address 10.1.1.1 255.255.255.0
speed auto
duplex auto
ipv6 address 2000::1/64
!
Step 1
Perform an ISSU upgrade to a Cisco IOS XE 3.4.0SG/15.1(2)SG image.
Step 2
Run the VRF upgrade command.
Switch#
config t
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#
vrf upgrade-cli multi-af-mode common-policies vrf mgmtVrf
You are about to upgrade to the multi-AF VRF syntax commands.
You will lose any IPv6 address configured on interfaces
belonging to upgraded VRFs.
Are you sure ? [
yes
]:
Number of VRFs upgraded:
1
Switch(config)#
exit
Your configuration will appear as follows:
vrf definition mgmtVrf
!
address-family ipv4
exit-address-family
!
interface FastEthernet1
vrf forwarding mgmtVrf
ip address 10.1.1.1 255.255.255.0
speed auto
duplex auto
!
Step 3
Configure the switch to enable the IPv6 address family and add the IPv6 address.
Switch#
config t
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#
vrf definition mgmtVrf
Switch(config-vrf)#
address-family ipv6
Switch(config-vrf-af)#
exit
Switch(config-vrf)#
exit
Switch(config)#
interface fa1
Switch(config-if)#
ipv6 address 2000::1/64
