Syntax

SHow -APPN CONNection [[netid.]cpname | ALL]

Shows connections to and from the local network node only.

Description

The CONNection parameter displays information about connections in the APPN network. The display includes connections associated with the network node topology only. The display shows the following:

• Links for the specified network node

• All links the network node is aware of

The display does not include connections between other network nodes and their associated end nodes.

Values

netid.	Specifies the net ID, although it is not required. If you do specify the net ID, you must enter a period after it, followed by the CP name with no space after the period. Net ID needs to be specified if the CP name has a different net ID than the local network node.
cpname | ALL	Specifies a CP name to be displayed. If you specify a CP name, you display a list of connections to the node with that CP name. If you specify ALL, you display a list of all connections for both the local topology and the network topology.
	When entering a CP name, you can enter either a non-qualified name (such as NB2GREEN) or a fully qualified name (such as US3COMHQ.NB2GREEN).
	If no value is specified, then only connections to the local network node are displayed.

To obtain the following display (showing all connections for both local and network topologies), enter the SHow -APPN CONNection ALL command. Table 16 describes the meanings of the headings and status messages included in the display.

Table 18 CONNection Display Meanings

Display Heading	Meaning
Node name	Node name for the connection. This will always be a network node, but may not necessarily be a 3Com bridge/router network node. If VRN is displayed, this indicates the node is acting as a virtual routing node. If the node name has an asterisk in front of it (as shown in the last line of the example), this indicates that the entry is not paired with its partner node in both directions, meaning the information may be stale in the network. If a node name is shown with an asterisk and the state is up, connectivity with the node may not be possible.
Partner name	Node name for the node at the remote end of the connection.
TG num	Number assigned to the transmission group between the two nodes. If you have parallel TGs between two nodes, one would be designated 1 and the other 2; also, with parallel TGs, one TG could be up while the other could be down.
State	Status of the connection: up or down. If both nodes are up, then the connection state will be up. If at least one node is down, then the connection state will be down.
RSN	Resource Sequence Number (RSN) for the TG. This indicates how up-to-date the information regarding the TG is. The higher the RSN number is, the more up-to-date the information. If you have two entries in the display showing the same TG, the entry with the higher RSN is more up-to-date. If the topology is stable, the RSN for the different network nodes would normally match.
