IP prefix list table

An IP prefix list specifies a list of networks. When you apply an IP prefix list to a neighbor, the Layer 3 Switch sends or receives only a route whose destination is in the IP prefix list. You can configure up to 100 prefix lists. The software interprets the prefix lists in sequential order, beginning with the lowest sequence number.

Name, OID, and Syntax

Access

Description

snIpPrefixListTable

1.3.6.1.4.1.1991.1.2.2.14

None

IP prefix list table.

snIpPrefixListEntry

1.3.6.1.4.1.1991.1.2.2.14.1

Syntax: SnIpPrefixListEntry

None An entry in the IP Prefix List table.
snIpPrefixListName

1.3.6.1.4.1.1991.1.2.2.14.1.1

Syntax: Octet String

Read-only

Specifies the name of the prefix list. This name can be used when applying the prefix list to a neighbor. It is an octet string; each character of the name is represented by one octet. There can be up to 32 octets for this name.

snIpPrefixListSequence

1.3.6.1.4.1.1991.1.2.2.14.1.2

Syntax: Integer32

Read-only

Shows the sequence of an entry in the table. There can be up to 100 prefix list entries. If a sequence number is not specified, then entries are numbered in increments of 5, beginning with prefix list entry 5. Incoming or outgoing routes are matched against the entries in the IP prefix list in numerical order, beginning with the lowest sequence number.

snIpPrefixListDesc

1.3.6.1.4.1.1991.1.2.2.14.1.3

Syntax: Octet String

Read-write

Specifies the description of the prefix. This description is in an octet string; each character in the description is represented by one octet. There can be up to 80 octets in the description.

snIpPrefixListAction

1.3.6.1.4.1.1991.1.2.2.14.1.4

Syntax: Integer

Read-write

Indicates what to do with the route if it matches this entry:

  • deny(0)
  • permit(1)
snIpPrefixListAddr

1.3.6.1.4.1.1991.1.2.2.14.1.5

Syntax: IpAddress

Read-write

Shows the IP address of the prefix.

snIpPrefixListMask

1.3.6.1.4.1.1991.1.2.2.14.1.6

Syntax: IpAddress

Read-write

Shows the number of bits in the prefix network mask.

snIpPrefixListGeValue

1.3.6.1.4.1.1991.1.2.2.14.1.7

Syntax: Integer

Read-write

Specifies that the prefix is greater than the value of the IP prefix list table object.

Valid values: 0 through 32

snIpPrefixListLeValue

1.3.6.1.4.1.1991.1.2.2.14.1.8

Syntax: Integer

Read-write

Specifies that the prefix is less than the value of the IP prefix list table object.

Valid values: 0 through 32

Note: You can specify a range of length for prefixes that are more specific than the values for the IP prefix list table and IP prefix list table objects. The ge-value or le-value you specify must meet the following condition: length < ge-value <= le-value <= 32

If a value for IP prefix list table is specified, then the mask-length range is from the value of IP prefix list table to 32.

If a value for IP prefix list table is specified, then mask-length range is from length to the value of IP prefix list table.

If no value is specified for either the less than or greater than objects, then routes must exactly match the prefixes on the list.

snIpPrefixListRowStatus

1.3.6.1.4.1.1991.1.2.2.14.1.9

Syntax: Integer

Read-write

Controls the management of the table rows. The values that can be written are:

  • delete(3) - Deletes the row
  • create(4) - Creates a new row
  • modify(5) - Modifies 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
