Symptom
This bug also affects Nexus 5000 as well as Nexus 7000.
Scenario 1:
When recovering Nexus 7000 configuration using an ASCII backup config some
parts of the config using 'source-interface' may fail if they are parsed
before the interface configuration. For example:
N7K-7010-1(config)# tacacs-server host 172.20.3.1 key 7 "fewhg"
N7K-7010-1(config)# aaa group server tacacs+ labserver
N7K-7010-1(config-tacacs+)# server 172.20.3.1
N7K-7010-1(config-tacacs+)# source-interface lopback11
^
Invalid interface format at '^' marker.
N7K-7010-1(config-tacacs+)# interface lo11
N7K-7010-1(config-if)# ip address 172.16.1.1/32
N7K-7010-1(config-if)#
Scenario 2:
TACACS service when sources from SVI which is not defined then gives
following error. This can also appear when doing a "copy bootflash:
running-configuration" that includes the "ip tacacs source-interface "
command.
switch# conf t
Enter configuration commands, one per line. End with CNTL/Z.
switch(config)# ip tacacs source-interface vlan20
^
Invalid range at '^' marker.
Conditions
Only applies to features that use 'source-interface' configuration and this
is in the ASCii config before the interface in question has been defined.
Workaround
First create interface vlan configuration so it parses after it.
