Cisco 7609

I having some fun and games getting my head around the Cisco 7609.

I have a picture of it (so I now know what it looks like :-)) and a set of four configs for one.  It appears that this particular box runs four seperate "partitions" - each config (all 4 configs are running concurrently on the same box) has a different hostname.

How does it run concurrent seperate configs? Is it partitioned in hardware or in the IOS? How's it all handled?

I've been poking around on the Cisco website for a couple of hours and I'm yet to attain enlightenment...

It doesn't. The chassis can only be configured as a whole entity, although there may be different configurations for the different feature cards. If the box is running hybrid mode, you will have separate configs for the supervisor card (which will be CatOS configs) and the MSFC card (which will be IOS). Additionally, feature cards like the FWSM (firewall module) and CSS (load balancing module) are configured separately to the rest of the box.

That said, the box doesn't run concurrent configs as such, more it needs to be configured in a number of different places when running with lots of additional feature cards.

What you have may well just be 4 different sample configs for the different ways the box could be configured?

Agree with andy_nD.

The box only runs on 1 config, but when you have separate blades then those blades will need configuration as well.  It's just like having a Cat 6506, you can configure the individual blades but when you need to configure the MSFC then you do, session 15.

If the box doesn't have any cards or blades, then those configs are there for different revisions.

It's a border router for a small-ish ISP - there are four configs for four different Telcos/entry points into the internet backbone running concurrently.

I gather that the stuff prefixed with ! in the config is the supervisor module config?

Are the config files for the blades standard IOS configs?

The blade config will depend on whether the box is running in hybrid or native mode. It's important to remember that the 7600 is still technically a switch with a router bolted on top, so technically there are two configurations that need to happen. The first is for the switch (i.e. supervisor) part of the device, which is where you configure things like port speed/duplex and VLAN memberships. The second is the router (i.e. MSFC) part of the device, which is where you configure IP addresses and routing protocols. In hybrid mode the switch configuration is done in CatOS, which will be a config with a lot of 'set' commands, and the router configuration is done in IOS. Native mode uses IOS for configuring both aspects of the device, which makes it possible to use one config for the entire box.

If you've got four configs for four different entry points, chances are you've only got snippets of the configurations required (interface speed/duplex/IP addresses, BGP sessions etc) that will be merged into the single configuration for the entire chassis.

Does each routing blade have it's own console port? Or is the entire config set up on the supervisor?
Only the supervisor has a console port. However, it is possible to manage the supervisor card 'in band' (i.e. over telnet/ssh/snmp) from any routable port (assuming no security access restrictions are in place)
