clear smrp mcache

To remove all fast-switching entries in the Sample Multicast Routing Protocol (SMRP) fast-switching cache table, use the clear smrp mcache command in EXEC mode.

clear smrp mcache

Syntax Description

This command has no arguments or keywords.

Command Modes

EXEC

Command History

Release	Modification
11.1	This command was introduced.

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.

---

Note Using this command clears the table of all entries, not just a single entry.

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.

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	Type and number of the interface.

Usage Guidelines

The show appletalk eigrp neighbors command lists only the neighbors running AppleTalk Enhanced IGRP. To list all neighboring AppleTalk routers, use the show appletalk neighbors command.

Examples

The following is sample output from the show appletalk eigrp neighbors command:

Router# show appletalk eigrp neighbors

Table 12 describes the fields shown in the display.

Table 12 show appletalk eigrp neighbors Field Descriptions 

Field	Description
process 1	Number of the Enhanced IGRP routing process.
router id 83	Autonomous system number specified in the appletalk routing global configuration command.
Address	AppleTalk address of the AppleTalk Enhanced IGRP peer.
Interface	Interface on which the router is receiving hello packets from the peer.
Holdtime	Length of time, in seconds, that the Cisco IOS software will wait to hear from the peer before declaring it down. If the peer is using the default hold time, this number will be less than 15. If the peer configures a nondefault hold time, it will be reflected here.
Uptime	Elapsed time, in hours, minutes, and seconds, since the local router first heard from this neighbor.
Q Count	Number of AppleTalk Enhanced IGRP packets (update, query, and reply) that the Cisco IOS software is waiting to send.
Seq Num	Sequence number of the last update, query, or reply packet that was received from this neighbor.
SRTT	Smooth round-trip time. This is the number of milliseconds it takes for an AppleTalk Enhanced IGRP packet to be sent to this neighbor and for the local router to receive an acknowledgment of that packet.
RTO	Retransmission timeout, in milliseconds. This is the amount of time the Cisco IOS software waits before retransmitting a packet from the retransmission queue to a neighbor.

Related Commands

Command	Description
appletalk routing	Enables AppleTalk routing.
show appletalk neighbors	Displays information about the AppleTalk routers that are directly connected to any of the networks to which this router is directly connected.

show appletalk eigrp topology

To display the AppleTalk Enhanced Interior Gateway Routing Protocol (EIGRP) topology table, use the show appletalk eigrp topology command in EXEC mode.

show appletalk eigrp topology [network-number | active | zero-successors]

Syntax Description

network-number	(Optional) Number of the AppleTalk network whose topology table entry you want to display.
active	(Optional) Displays the entries for all active routes.
zero-successors	(Optional) Displays the entries for destinations for which no successors exist. These entries are destinations that the Cisco IOS software currently does not know how to reach via Enhanced IGRP. This option is useful for debugging network problems.

Command Modes

EXEC

Command History

Release	Modification
10.3	This command was introduced.

Usage Guidelines

All Enhanced IGRP routes that are received for a destination, regardless of metric, are placed in the topology table. The route to a destination that is currently in use is the first route listed. Routes that are listed as "connected" take precedence over any routes learned from any other source.

Examples

The following is sample output from the show appletalk eigrp topology command:

Router# show appletalk eigrp topology 

IPX EIGRP Topology Table for process 1, router id 1

Table 13 describes the fields that may be displayed in the output.

Table 13 show appletalk eigrp topology Field Descriptions 

Field	Description
Codes:	State of this topology table entry. Passive and Active refer to the Enhanced IGRP state with respect to this destination; and Update, Query, and Reply refer to the type of packet that is being sent.
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.
R - Reply	Indicates that a reply packet was sent to this destination.
r - Reply status	Flag that is set after the Cisco IOS software has sent a query and is waiting for a reply.
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.
(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.
Ethernet0	Interface from which this information was learned.
