Usage Guidelines
Use this command to clear the SMRP fast-switching cache table. The SMRP fast-switching cache table contains the information needed to fast switch SMRP data packets. It is usually unnecessary to clear the table; however, you can do so to repopulate it or to clear a corrupted entry.

P - Passive | No Enhanced IGRP computations are being performed for this destination. |
A - Active | Enhanced IGRP computations are being performed for this destination. |
U - Update | Indicates that an update packet was sent to this destination. |
Q - Query | Indicates that a query packet was sent to this destination. |

3165, 3161, and so on | 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. |

Table 14 describes the fields that may appear in the output.
| Field | Description |
|---|---|
3165 | AppleTalk network number of the destination. |
State is ... | State of this entry. It can be either Passive or Active. Passive means that no Enhanced IGRP computations are being performed for this destination, and Active means that they are being performed. |
Query origin flag | 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. |
Successors | Number of successors. This number corresponds to the number of next hops in the IPX routing table. |
Next hop is ... | Indicates how this destination was learned. It can be one of the following:
|
Ethernet0 | Interface from which this information was learned. |
from | Peer from whom the information was learned. For connected and redistributed routers, this is 0.0. For information learned via Enhanced IGRP, this is the peer's address. Currently, for information learned via Enhanced IGRP, the peer's AppleTalk address always matches the address in the "Next hop is" field. |
Composite metric is | Enhanced IGRP composite metric. The first number is this device's metric to the destination, and the second is the peer's metric to the destination. |
Send flag | Numeric representation of the "flags" field. It is 0 when nothing is being sent, 1 when an Update is being sent, 3 when a Query is being sent, and 4 when a Reply is being sent. Currently, 2 is not used. |
Route is ... | Type of router. It can be either internal or external. Internal routes are those that originated in an Enhanced IGRP autonomous system, and external routes are those that did not. Routes learned via RTMP are always external. |
Vector metric: | This section describes the components of the Enhanced IGRP metric. |
Minimum bandwidth | Minimum bandwidth of the network used to reach the next hop. |
Total delay | Delay time to reach the next hop. |
Reliability | Reliability value used to reach the next hop. |
Load | Load value used to reach the next hop. |
Minimum MTU | Smallest Maximum Transmission Unit (MTU) size of the network used to reach the next hop. |
Hop count | Number of hops to the next hop. |
External data | This section describes the original protocol from which this route was redistributed. It appears only for external routes. |
Originating router | Network address of the router that first distributed this route into AppleTalk Enhanced IGRP. |
External protocol metric delay | External protocol from which this route was learned. The metric will match the external hop count displayed by the show appletalk route command for this destination. The delay is the external delay. |
Administrator tag | Currently not used. |
Flag | Currently not used. |

Table 20 describes the fields shown in the display.
| Field | Description |

MACIP SERVER 1 | Number of the MacIP server. This number is assigned arbitrarily. |
IP 131.108.199.221 | 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 131.108.199.1-131.108.199.10, 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 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.

|---|---|
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. |

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:
