This chapter explains the function and syntax of the DECnet protocol commands: decnet output-routing filter through show decnet traffic. For more information about defaults and usage guidelines, see the corresponding chapter of the Cisco IOS Apollo Domain, Banyan VINES, DECnet, ISO CLNS, and XNS Command Reference, Release 12.1.
Syntax Description
access-list-number Standard DECnet access list applying to source addresses. The value can be in the range 300 to 399.
To specify how the Cisco IOS software splits the routable packets between equal-cost paths, use the decnet path-split-mode command with the appropriate keyword in global configuration mode.
decnet path-split-mode {normal | interim}
Syntax Description
normal Normal mode, where equal-cost paths are selected on a round-robin basis. This is the default. interim Traffic for any particular (higher-layer) session is always routed over the same path. This mode supports older implementations of DECnet (VMS Versions 4.5 and earlier) that do not support out-of-order packet caching. Other sessions may take another path, thus using equal-cost paths that a router may have for a particular destination.
To enable static route propagation, use the decnet propagate static command in global configuration mode. To disable propagation, use the no form of this command.
decnet propagate staticSyntax Description
This command has no arguments or keywords.
To create an interface static route, use this version of the decnet route command in global configuration mode. To remove this route, use the no form of this command.
decnet route decnet-address next-hop-type number [snpa-address] [hops [cost]]
Syntax Description
decnet-address DECnet address. This value is entered into a static routing table and used to match a destination DECnet address. Use a node address value of 0 to specify an area static route. next-hop-type Interface type. number Interface number. snpa-address (Optional) Optional for serial links; required for multiaccess networks. hops (Optional) Hop count to be associated with the route being advertised. Default is 0. cost (Optional) Cost to be associated with the route being advertised. Default is 0.
To enter a specific static route, use this version of the decnet route command in global configuration mode. DECnet addresses that match are forwarded to the next-hop-address. To remove this route, use the no form of this command.
decnet route decnet-address next-hop-address [hops [cost]]
Syntax Description
decnet-address DECnet address. This value is entered into a static routing table and used to match a destination DECnet address. Use a node address value of 0 to specify an area static route. next-hop-address This value is used to establish the next hop of the route for forwarding packets. hops (Optional) Hop count to be associated with the route being advertised. Default is 0. cost (Optional) Cost to be associated with the route being advertised. Default is 0.
To create an interface default route, use this version of the decnet route default command in global configuration mode. To remove this route, use the no form of this command.
decnet route default next-hop-type number [snpa-address] [hops [cost]]
Syntax Description
next-hop-type Interface type. number Interface number. snpa-address (Optional) Optional for serial links; required for multiaccess networks. hops (Optional) Hop count to be associated with the route being advertised. Default is 0. cost (Optional) Cost to be associated with the route being advertised. Default is 0.
To enter a specific default route, use this version of the decnet route default command in global configuration mode. To remove this route, use the no form of this command.
decnet route default next-hop-address [hops [cost]]
Syntax Description
next-hop-address This value is used to establish the next hop of the route for forwarding packets. hops (Optional) Hop count to be associated with the route being advertised. Default is 0. cost (Optional) Cost to be associated with the route being advertised. Default is 0.
Syntax Description
This command has no arguments or keywords.
To elect a designated router to which packets are sent when no destination is specified, use the decnet router-priority command in interface configuration mode.
decnet router-priority value
Syntax Description
value Priority of the router. This can be a number in the range 0 to 127. The larger the number the higher the priority. The default priority is 64.
To enable DECnet routing, use the decnet routing command in global configuration mode. To disable DECnet routing, use the no form of this command.
decnet [network-number] routing [iv-prime] decnet-address
Syntax Description
network-number (Optional) Network number in the range 0 to 3. Specified when using ATG. If not specified, the default is network 0. iv-prime (Optional) Enables DECnet Phase IV Prime routing. decnet-address Address in DECnet format X.Y, where X is the area number and Y is the node number.
Syntax Description
seconds Time, in seconds, from 1 to 65535. The default is 40 seconds.
To use split horizon when sending routing updates, use the decnet split-horizon command in interface configuration mode. To disable split horizon, use the no form of this command.
decnet split-horizonSyntax Description
This command has no arguments or keywords.
To set the delayed acknowledgment for incoming LAT slave connections, use the lat host-delay command in global configuration mode. To restore the default, use the no form of this command.
lat host-delay number
Syntax Description
number The delay in milliseconds.
To associate a command with a service, use the lat service autocommand command in global configuration mode. To remove the specified autocommand, use the no form of this command.
lat service service-name autocommand command
Syntax Description
service-name Name of the service. command Command to be associated with the service.
To display the global DECnet parameters, use the show decnet command in privileged EXEC mode.
show decnetSyntax Description
This command has no arguments or keywords.
To display the active accounting or checkpointed database, use the show decnet accounting command in EXEC mode.
show decnet accounting [checkpoint]
Syntax Description
checkpoint (Optional) Displays entries in the checkpoint database.
To display the global DECnet status and configuration for all interfaces or the status and configuration for a specified interface, use the show decnet interface command in EXEC mode.
show decnet interface [type number]
Syntax Description
type (Optional) Interface type. number (Optional) Interface number.
To display the address mapping information used by the DECnet Address Translation Gateway, use the show decnet map command in EXEC mode.
show decnet mapSyntax Description
This command has no arguments or keywords.
To display all Phase IV and Phase IV Prime adjacencies and the MAC address associated with each neighbor, use the show decnet neighbors command in privileged EXEC mode.
show decnet neighborsSyntax Description
This command has no arguments or keywords.
To display the DECnet routing table, use the show decnet route command in EXEC mode.
show decnet route [decnet-address]
Syntax Description
decnet-address (Optional) DECnet address when specified, the first hop route to that address is displayed.
To display all statically configured DECnet routes, use the show decnet static command in privileged EXEC mode.
show decnet staticSyntax Description
This command has no arguments or keywords.
To show the DECnet traffic statistics (including datagrams sent, received, and forwarded), use the show decnet traffic command in EXEC mode.
show decnet trafficSyntax Description
This command has no arguments or keywords.
