Table 13-29. ARP Configuration Subgroup OIDs

OID

Description

cimFlushArpTable

Can be used to flush the non-static ARP table.

The cimArpTable is used to configure the static ARP table. This table allows up to 256 static ARP entries. The Static ARP entries provided by the CiM-550 fall into two categories: IP-to-MAC and IP-to-HDLC.

Note: For the CiM-550 to properly route packets over the Satellite Interface, all of the Next Hop Addresses in the route table MUST have an IP-to-HDLC mapping in the static ARP table. Incoming packets that match a route in the route table that does not have an IP-to-HDLC mapping in the static ARP table will be discarded.

Table 13-30. CiM ARP Table OIDs

OID

Description

 

 

cimArpIndex

Sequential number that corresponds to the row index in the

 

ARP table. The ARP entry index starts at 1.

cimArpIpAddress

Used as a lookup into the ARP table when the CiM-550

 

needs to resolve a MAC or HDLC Address. The IP Address

 

must be on the same subnet as the Ethernet or Satellite

 

Interfaces. It must not map to multiple HDLC or MAC

 

addresses. The IP Address must be a valid Unicast address.

cimArpPhysAddress

This can either be a MAC address or a HDLC address. Valid

 

MAC addresses are in the form “xx:xx:xx:xx:xx:xx”, where “x”

 

represents any HEX number. Valid HDLC addresses are

 

number from 1 to 65534 that represent HEX numbers

 

between 1 – FFFE.

cimArpPhysType

Indicates if the ARP entry is an IP-to-MAC or an IP-to-HDLC

 

translation.

 

 

 

This OID can be set to:

 

 

 

 

 

 

1

IP To MAC

 

 

 

 

 

 

 

 

2

IP To HDLC
