Static ARP table

Static ARP table
The Address Resolution Protocol (ARP) is a standard IP protocol that enables an IP Layer 3 Switch
to obtain the MAC address of another device’s interface when the Layer 3 Switch knows the IP
address of the interface. ARP is enabled by default and cannot be disabled.
The static ARP table in a Layer 3 Switch contains entries that are useful in cases where you want to
preconfigure an entry for a device that is not connected to the Layer 3 Switch, 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 or not the device receives an ARP request from the device that has the
entry’s address.
NOTE
The following table is not supported on the Brocade MLXe, Brocade NetIron MLX, Brocade NetIron
XMR, Brocade NetIron CES, and Brocade NetIron CER series devices.
Name, OID, and syntax Access Description
snRtIpRarpTable
brcdIp.1.2.2.4 None IP RARP table.
snRtIpRarpIndex
brcdIp.1.2.2.4.1.1
Syntax: Integer Read-only An index for an entry in the RARP table. There can be up to 16 entries.
snRtIpRarpMac
brcdIp.1.2.2.4.1.2
Syntax: OCTET STRING Read-write Shows the MAC address of the RARP client.
snRtIpRarpIp
brcdIp.1.2.2.4.1.3
Syntax: IpAddress Read-write Shows the IP address for a RARP client.
snRtIpRarpRowStatus
brcdIp.1.2.2.4.1.4
Syntax: Integer Read-write Controls the management of the table rows. The following values can be
written:
•
delete(3) – Delete the row.
•
create(4) – Create a new row.
•
modify(5) – Modify an existing row.
If the row exists, then a SET with a value of create(4) returns a "bad
value" error. Deleted rows are removed from the table immediately.
The following values can be returned on reads:
•
noSuch(0) – No such row.
•
invalid(1) – Row is inoperative.
•
valid(2) – Row exists and is valid.
