Enabling FDP at the interface level
By default, FDP is enabled at the interface level after FDP is enabled on the device.
When FDP is enabled globally, you can disable and re-enable FDP on individual ports.
Disable FDP by entering commands such as the following:
device(config)# int e 2/1
device(config-if-2/1)# no fdp enable
Enable or repenable FDP by entering commands such as the following:
device(config-if-2/1)# fdp enable
Syntax:
[no] fdp
enable
Specifying the IP management address to advertise
When FDP is enabled, by default, the Brocade device advertises one IPv4 address and one IPv6
address to its FDP neighbors. If desired, you can configure the device to advertise only the IPv4
management address or only the IPv6 management address. You can set the configuration globally
on a Layer 2 switch, or on an interface on a Layer 3 switch.
For example, to configure a Layer 2 switch to advertise the IPv4 address, enter the following
command at the Global CONFIG level of the CLI:
device(config)# fdp advertise ipv4
To configure a Layer 3 switch to advertise the IPv6 address, enter the following command at the
Interface level of the CLI:
device(config-if-2/1)# fdp advertise ipv6
Syntax:
fdp advertise
ipv4
|
ipv6
Changing the FDP update timer
By default, a Brocade device enabled for FDP sends an FDP update every 60 seconds. You can
change the update timer to a value from 5 - 900 seconds.
To change the FDP update timer, enter a command such as the following at the global CONFIG level
of the CLI.
device(config)# fdp timer 120
Syntax:
[no] fdp
timer
secs
The
secs
parameter specifies the number of seconds between updates and can be from 5 - 900
seconds. The default is 60 seconds.
Changing the FDP hold time
By default, a Brocade device that receives an FDP update holds the information until one of the
following events occurs:
• The device receives a new update.
• 180 seconds have passed since receipt of the last update. This is the hold time.
Once either of these events occurs, the device discards the update.
