Table 6 show appletalk arp Field Descriptions 

Field
Description

Address

AppleTalk network address of the interface.

Age (min)

Time, in minutes, that this entry has been in the ARP table. Entries are purged after they have been in the table for 240 minutes (4 hours). A hyphen indicates that this is a new entry.

Type

Indicates how the ARP table entry was learned. It can be one of the following:

Dynamic—Entry was learned via AARP.

Hardware—Entry was learned from an adapter in the router.

Pending—Entry for a destination for which the router does not yet know the address. When a packet requests to be sent to an address for which the router does not yet have the MAC-level address, the Cisco IOS software creates an AARP entry for that AppleTalk address, then sends an AARP Resolve packet to get the MAC-level address for that node. When the software gets the response, the entry is marked "Dynamic." A pending AARP entry times out after 1 minute.

Hardware Addr

MAC address of this interface.

Encap

Encapsulation type. It can be one of the following:

ARPA—Ethernet-type encapsulation

Subnetwork Access Protocol (SNAP)—IEEE 802.3 encapsulation

Interface

Destination AppleTalk network number.

successors

Number of successors. This number corresponds to the number of next hops in the AppleTalk routing table.

FD

Feasible distance. This value is used in the feasibility condition check. If the neighbor's reported distance (the metric after the slash) is less than the feasible distance, the feasibility condition is met and that path is a feasible successor. Once the software determines it has a feasible successor, it does not have to send a query for that destination.

replies

Number of replies that are still outstanding (have not been received) with respect to this destination. This information appears only when the destination is in the Active state.

state

Exact Enhanced IGRP state that this destination is in. It can be the number 0, 1, 2, or 3. This information appears only when the destination is Active.

via

AppleTalk address of the peer who told the software about this destination. The first n of these entries, where n is the number of successors, are the current successors. The remaining entries on the list are feasible successors.

(345088/319488)

The first number is the Enhanced IGRP metric that represents the cost to the destination, The second number is the Enhanced IGRP metric that this peer advertised to us.

Usage Guidelines

The information in the show appletalk macip-servers display can help you quickly determine the status of your MacIP configuration. In particular, the STATE field can help identify problems in your AppleTalk environment.

Examples

The following is sample output from the show appletalk macip-servers command:

Router# show appletalk macip-servers

MACIP SERVER 1, IP 172.18.199.221,  ZONE 'S/W Test Lab' STATE is server_up
Resource #1 DYNAMIC 172.18.199.1-172.18.199.10, 1/10 IP in use
Resource #2 STATIC 172.18.199.11-172.18.199.20, 0/10 IP in use

Table 20 describes the fields shown in the display.

Table 20 show appletalk macip-servers Field Descriptions 

Field
Description

MACIP SERVER 1

Number of the MacIP server. This number is assigned arbitrarily.

IP 172.18.199.221

IP address of the MacIP server.

ZONE `S/W Test Lab'

AppleTalk server zone specified with the appletalk macip server command.

STATE is server_up

State of the server. Table 22 lists the possible states.

If the server remains in the "resource_wait" state, check that resources have been assigned to this server with either the appletalk macip dynamic or the appletalk macip static command.

Resource #1 DYNAMIC 172.18.199.1-172.18.199.10, 1/10 IP in use

Resource specifications defined in the appletalk macip dynamic and appletalk macip static commands. This list indicates whether the resource address was assigned dynamically or statically, identifies the IP address range associated with the resource specification, and indicates the number of active MacIP clients.


Use the show appletalk macip-servers command with show appletalk interface to identify AppleTalk network problems, as follows:


Step 1 Determine the state of the MacIP server using show appletalk macip-servers. If the STATE field continues to indicate an anomalous status (something other than "server_up," such as "resource_wait" or "zone_wait"), there is a problem.

Step 2 Determine the status of AppleTalk routing and the specific interface using the show appletalk interface command.

Step 3 If the protocol and interface are up, check the MacIP configuration commands for inconsistencies in the IP address and zone.


The STATE field of the show appletalk macip-servers command indicates the current state of each configured MacIP server. Each server operates according to the finite-state machine table described in Table 21. Table 22 describes the state functions listed in Table 21. These are the states that are displayed by the show appletalk macip-servers command.

Table 22 Server States 

State
Description

ck_resource

The server verifies that at least one client range is available. If not, it deregisters NBP names and returns to the resource_wait state.

del_server

State at which all servers end. In this state, the server deregisters all NBP names, purges all clients, and deallocates server resources.

initial

The state at which all servers start.

resource-wait

The server waits until a client range for the server has been configured.

send_confirms

The server tickles active clients every minute, deletes clients that have not responded within the last 5 minutes, and checks IP and AppleTalk interfaces used by MacIP server. If the interfaces are down or have been reconfigured, the server restarts.

server_start

The server registers configured IPADDRESS and registers as IPGATEWAY. It then opens an ATP socket to listen for IP address assignment requests, sends NBP lookup requests for existing IPADDRESSes, and automatically adds clients with addresses within one of the configured client ranges.

server_up

The server has registered. Being in this state enables routing to client ranges. The server now responds to IP address assignment requests.

zone_wait

The server waits until the configured AppleTalk zone name for the server is up. The server will remain in this state if no such zone has been configured or if AppleTalk routing is not enabled.

*

An asterisk in the first column represents any state. An asterisk in the second column represents a return to the previous state.

This command was introduced.


Usage Guidelines

The show appletalk name-cache command displays the information currently in the NBP name cache.

Support for names allows you to easily identify and determine the status of any associated device. This can be important in AppleTalk internetworks where node numbers are dynamically generated.

You can authorize the show appletalk name-cache command to display any AppleTalk services of interest in local zones. This contrasts with the show appletalk nbp command, which you use to display services registered by routers.

Examples

The following is sample output from the show appletalk name-cache command:

Router# show appletalk name-cache

AppleTalk Name Cache:
Net     Adr  Skt  Name                 Type             Zone

This command was introduced.


Usage Guidelines

The show appletalk nbp command lets you identify specific AppleTalk nodes. It displays services registered by the router. In contrast, use the show appletalk name-cache command to display any AppleTalk services of interest in local zones.

Routers with active AppleTalk interfaces register each interface separately. The Cisco IOS software generates a unique interface NBP name by appending the interface type name and unit number to the router name. For example, for the router named "router" that has AppleTalk enabled on Ethernet interface 0 in the zone Marketing, the NBP registered name is as follows:

router.Ethernet0:ciscoRouter@Marketing

Registering each interface on the router provides you with an indication that the device is configured and operating properly.

One name is registered for each interface. Other service types are registered once for each zone.

The Cisco IOS software deregisters the NBP name if AppleTalk is disabled on the interface for any reason.

Examples

The following is sample output from the show appletalk nbp command:

Router# show appletalk nbp

Net  Adr Skt Name                    Type            Zone
