Does it exist with brocade?

Thanks

Re: Brocade equivalent to cisco CDP

Hi gagnon,

     Yes it does.

Enabling FDP globally

To enable a Brocade device to globally send FDP packets, enter the following command at the

global CONFIG level of the CLI.

FastIron(config)# fdp run

Syntax: fdp run

The feature is disabled by default.

Enabling FDP at the interface level

You can enable FDP at the interface level by entering commands such as the following.

FastIron(config)# int e 2/1

FastIron(config-if-2/1)# fdp enable

Syntax: fdp enable

By default, the feature is enabled on an interface once FDP is enabled on the device.

Re: Brocade equivalent to cisco CDP

I do not think so.  I think FDP is Foundry/Brocade devices only.

CDP is Cisico devices only.

However you can configure the Brocade device to read CDP, but see the notes if this will work for you.

Reading CDP packets

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.

Enabling interception of CDP packets globally

To enable the device to intercept and display CDP packets, enter the following command at the global CONFIG level of the CLI.

FastIron(config)# cdp run

Syntax: cdp run

The feature is disabled by default.

Enabling interception of CDP packets on an interface

You can disable and enable CDP at the interface level. You can enter commands such as the following.

FastIron(config)# int e 2/1

FastIron(config-if-2/1)# cdp enable

Syntax: cdp enable

By default, the feature is enabled on an interface once CDP is enabled on the device.

Displaying CDP information

You can display the following CDP information:

Cisco neighbors

CDP entries for all Cisco neighbors or a specific neighbor

CDP packet statistics

Displaying neighbors

To display the Cisco neighbors the Brocade device has learned from CDP packets, enter the

following command.

To display detailed information for the neighbors, enter the following command.

To display information about a neighbor attached to a specific port, enter a command such as the following.

Syntax: show fdp neighbors

<portnum>]

Displaying CDP entries

To display CDP entries for all neighbors, enter the following command.

FastIron# show fdp neighbors
