What I have always wanted is a way to group configuration, in particular =
by customer. Ideally with the ability to see it both as a unified view, =
and also as a per-customer view.
For instance:
customer AAAAA
interface GigabitEthernet1/2/3.10
description AAAAA
ip address 10.0.1.1 255.255.255.0
router bgp 1
neighbor 10.0.1.2 prefix-list AAAAA-in in
ip prefix-list AAAAA-in 10.1.0.0/24
end
customer BBBBB
interface GigabitEthernet1/2/3.11
description BBBBB
ip address 10.0.2.1 255.255.255.0
router bgp 1
neighbor 10.0.2.2 prefix-list BBBBB-in in
ip prefix-list BBBBB-in 10.2.0.0/24
end
Then I should be able to do:
show run - Normal output like we see today, the "device" view.
customer AAAAA show run - Same format as I have above, just config =
relevant to customer AAAAA.
I can even see extending the tag to work with some other commands:
customer AAAAA show int
customer AAAAA show bgp ipv4 uni sum
customer AAAAA show ip prefix-list
The same functionality would work for snippets:
customer ntp-servers-v1.0
ntp server 1.2.3.4
ntp server 1.2.3.5
ntp server 1.2.3.6
end
Basically this follows the two modes in which engineers look at a =
device. Most of the time is configuring a specific customer, and =
wanting to be sure they are configured right; including the hard case of =
"no customer AAAAA", that is making sure all configuration for a =
specific customer is removed. The rest of the time is typically =
troubleshooting a network level problem where you want the device view =
we have today, I see interface Gig1/2/3 is dropping packets, "show run" =
to see who's configure on it sort of operations.
I don't know of any platform that has implemented this sort of config =
framework though.
