[f-nsp] cdp sending by BRCD devices

[Kennedy, Joseph]

>From the FI8001 administration guide:

...

Cisco Discovery Protocol (CDP) packets are used by Cisco devices to advertise themselves to other Cisco devices. By default, Brocade devices forward these packets without examining their contents. You can configure a Brocade device to intercept and display the contents of CDP packets. This feature is useful for learning device and interface information for Cisco devices in the network.

Brocade devices support intercepting and interpreting CDP version 1 and version 2 packets.

NOTE: The Brocade device can interpret only the information fields that are common to both CDP version 1 and CDP version 2.
NOTE: When you enable interception of CDP packets, the Brocade device drops the packets. As a result, Cisco devices will no longer receive the packets.
…

Intercept and display only.

FYI if you start running LLDP:

…

Enabling support for tagged LLDP packets

By default, Brocade devices do not accept tagged LLDP packets from other vendors’ devices. To enable support, apply the command lldp tagged-packets process at the Global CONFIG level of the CLI. When enabled, the device will accept incoming LLDP tagged packets if the VLAN tag matches any of the following:

- a configured VLAN on the port
- the default VLAN for a tagged port
- the configured untagged VLAN for a dual-mode port

To enable support for tagged LLDP packets, enter the following command.

device(config)#lldp tagged-packets process

Hi
Is any way to enable ICX/FastIron switches to send CDP packets ?
I enabled 'cdp run' but I only see my Cisco neighbors, but they don't see me.

I can run LLDP, yeah. But would like to stay with CDP if possible.
