ROUte

Syntax

ADD !<port> -SR ROUte <media address> [Override] [Dec | Hex] [ Transparent | {Null | <source route> [<largestframesize>]}]
DELete !<port> -SR ROUte <media address>
SHow [!<port> | !*] -SR ROUte [[Cmac | Ncmac] %<media address>] [Dec | Hex]
SHowDefault [!<port> | !*] -SR ROUte [[Cmac | Ncmac] %<media address>] [Dec |Hex]

Default

No default

Description

The ROUte parameter configures, deletes, and displays a static route for a remote end system.

Values

<media address>

Specifies the media address of a remote station. Must be 12 hexadecimal digits and preceded by a percent sign (%).

Use the Cmac keyword when the media address is entered in canonical format and the Ncmac keyword when the media address is entered in noncanonical format.

If neither Cmac nor Ncmac is specified, the current setting of the -SYS MacAddrFormat parameter is used.

Override

Specifies that the static route can be replaced by a learned route if the route has been determined to be inoperational.

Dec | Hex

Specifies that the route information is entered or displayed in decimal (Dec keyword) or hexadecimal format (Hex keyword).

Transparent

Specifies that no RIF be used on frames sent to the specified address; the target is on the local ring or reached via transparent bridges. The default is a transparent spanning tree route.

Null

Specifies that a null RIF is used; the target is on the local ring.

<source route>

Specifies a source as a sequence of rings and bridges in the order in which a source-routed packet traverses the source route bridged network. The route is specified as follows:

:<ring_number>&<bridge_number>[:<ring_number>]...

A ring number must be preceded by a colon (:), and a bridge number must be preceded by an ampersand (&). The following is an example of a route where the source route packet initiated at Ring 25 is forwarded through Bridge 2 onto Ring 4 before reaching its end system destination:

:25&2:4

A valid route must begin with a ring number that matches the ring number assigned to the specified port. If the last element specified in <route> is a bridge number, that element is ignored.

<largestframesize>

Specifies the largest size MAC frame that can be transmitted to the indicated end system using this route. An integer value of 0 through 7 may be assigned. The default value is 3. The base values specified in IEEE 802.1D are supported; however, extended values are not currently supported. Enter one of the following numbers for the largest frame size value:

0 for 516 bytes
1 for 1,470 bytes
2 for 2,052 bytes
3 for 4,399 bytes
4 for 8,130 bytes (not supported)
5 for 11,407 bytes (not supported)
6 for 17,749 bytes (not supported)
7 for 41,600 bytes (not supported)
