Adding a static ARP entry
NOTE
Adding a static ARP entry is supported on FastIron X Series, Brocade FCX Series, ICX 6610 and ICX 6450 devices.
Static entries are useful in cases where you want to pre-congure an entry for a device that is not connected to the Brocade device, or
you want to prevent a particular entry from aging out. The software removes a dynamic entry from the ARP cache if the ARP aging
interval expires before the entry is refreshed. Static entries do not age out, regardless of whether the Brocade device receives an ARP
request from the device that has the entry address. The software places a static ARP entry into the ARP cache as soon as you create the
entry.
To add a static ARP entry, enter a command such as the following at the global CONFIG level of the CLI.
device(config)#arp 10.157.22.3 0000.00bb.cccc ethernet 3
This command adds a static ARP entry that maps IP address 10.157.22.3 to MAC address 0000.00bb.cccc. The entry is for a MAC
address connected to device port 3.
Syntax: [no] arp ip-addrmac-addr ethernet port
The ip-addr variable
species the IP address of the device that has the MAC address of the entry.
The mac-addr variable species the MAC address of the entry.
The ethernet port parameter species the port number attached to the device that has the MAC address of the entry. Specify the port
variable in one of the following formats:
The clear arp command clears learned ARP entries but does not remove any static ARP entries.
Modifying and displaying Layer 3 system parameter
limits
This section shows how to view and
congure some of the Layer 3 system parameter limits.
Layer 3 conguration notes
• Changing the system parameters recongures the device memory. Whenever you recongure the memory on a Brocade
device, you must save the change to the startup-cong le, and then reload the software to place the change into eect.
• The Layer 3 system parameter limits for FastIron IPv6 models are automatically adjusted by the system and cannot be
manually modied.
FastIron second generation modules
FastIron IPv6 models support the same Layer 3 system parameters that use hardware memory as do FastIron IPv4 models. However,
there are some conguration dierences between second generation modules and rst generation modules. The dierences are as
follows:
• Number of IP next hops - 6144 maximum and default value.
• Number of multicast output interfaces (clients) - 3072 maximum. This value is xed in second generation modules and cannot
be modied. This system parameter occupies its own hardware memory space.
To display the current settings for the Layer 3 system parameters, use the show default value command.
