Default Gateway on CSS 11154

[dwalsh]

Hello,

I just set up my CSS 11154 and I assigned the IP address to the Mgmt interface. I can ping it if I'm on the same subnet, but if I'm across a routed interface, I can not. I didn't see anywhere to put in a "default-gateway" parameter like on at regular switch. So, I just put in the

ip route 0.0.0.0 0.0.0.0 10.1.0.1

statement, thinking that would do the trick. It doesn't work. Any suggestions. Here's my config:

CSS11150# show run

!Generated on 01/01/1981 00:00:34

!Active version: ap0500033

configure

you can configure 'ip management route ...' but no default gateway.

Also, be careful that you can't have the same route pointing to management interface and to a regular interface.

Also the command above comes only in recent versions.

Hi Gilles,

It doesn't appear as though the "ip management route" is a valid command. Here's my version and what I have as options when issuing the "ip" command:

CSS11150(config)# version

Version: ap0500033 (5.00 Build 33)

Flash (Locked): 5.00 Build 33

Flash (Operational): 5.00 Build 33

Type: PRIMARY

Licensed Cmd Set(s): Standard Feature Set

CSS11150(config)# ip ?

ecmp Set the equal-cost multipath selection algorithm

firewall Configure firewall load-balancing route

no-implicit-service Do not start an implicit service for the next hop of

static routes

opportunistic Set the IP opportunistic layer-3 forwarding mode

record-route Enable processing of frames with a record-route option

redundancy Enable box-to-box redundancy

route Configure a static route

source-route Enable processing of source-routed frames

subnet-broadcast Enable forwarding of subnet broadcast addressed frames

uncond-bridging Do not allow routing lookup to override bridging decision

CSS11150(config)# ip

Any suggestions?

Also, your comment regarding "you can't have the same route pointing to a management interface and to a regula interface." What does that mean. I'm treating these things as basically the same as a regular 29xx/35xx switch, but there are definitely differences.

Thanks,

Dave

Dave,

from my last post

"Also the command above comes only in recent versions. "

Do you think that 5.0(0.33) is recent ?

.

no - this version is 2 years old.

You need the latest 6.10 for the command mentioned.

Using the search engine you could find the documentation for the command.

Also, the CSS is TOTALLY different from any other Cisco switch. The CSS was acquired from Arrowpoint and therefore is a different concept.

Hi Gilles,

This worked like a charm. Once I upgraded to 6.10x, I had the ability to route traffic to/from the Mgmt interface. It wouldn't let me put in a default route, but that doesn't matter. I just put in a static route and that did the trick.

Now I just have to get my head wrapped around Circuits and stuff. I'm a bit confused as to why VLANs (just another name for "circuits" I think) have IP address information associated to them. I don't understand why an L2 interface has an IP address assigned. But I'll see what I can find out about that.

Thanks,

Dave

Dave,

glad to hear you found the command you needed in 6.10

Regarding ip addresses and vlans, switches nowadays separate the physical interface from the logical interface.

The circuit or vlan is the logical interface.

You assign it an ip address.

Physical interface can be grouped into logical interfaces.

For example, you could group e1 and e2 under vlan 100 and e3 under vlan 200.

The CSS will bridge traffic from e1 to e2 and will route traffic from e3 to e1 or e2.

Hoep this helps.

Gilles.
