The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

The show interface mac command displays information for one interface, when specified, or all interfaces configured for MAC accounting.
For incoming packets on the interface, the accounting statistics are gathered before the committed access rate (CAR)/distributed committed access rate (DCAR) functionality is performed on the packet. For outgoing packets on the interface, the accounting statistics are gathered after the CAR output, and before DCAR output or distributed weighted random early detection (DWRED) or distributed weighted fair queuing (DWFQ) functionality is performed on the packet.
Therefore, if DCAR or DWRED is performed on the interface and packets are dropped, the dropped packets are still counted in the show interface mac command.
The maximum number of MAC addresses that can be stored for the input and output addresses is 512 each. After the maximum is reached, subsequent MAC addresses are ignored.
To clear the accounting statistics, use the clear counter EXEC command. To configure an interface for IP accounting based on the MAC address, use the ip accounting mac-address interface configuration command.
The following is sample output from the show interface mac command:
Router# show interface ethernet 0/1/1 mac Ethernet0/1/1 Input (511 free) 0007.f618.4449(228): 4 packets, 456 bytes, last: 2684ms ago Total: 4 packets, 456 bytes Output (511 free) 0007.f618.4449(228): 4 packets, 456 bytes, last: 2692ms ago Total: 4 packets, 456 bytes

The show ip sctp association parameters command provides information to determine the stability of SCTP associations, dynamically calculated statistics about destinations, and values to assess network congestion. This command also displays parameter values for the specified association.
This command requires an association identifier. Association identifiers can be obtained from the output of the show ip sctp association list command.
Many parameters are defined for each association. Some are configured parameters, and others are calculated. Three main groupings of parameters are displayed by this command:
The association configuration section displays information similar to that in the show ip sctp association list command, including association identifiers, state, and local and remote port and address information. The current primary destination is also displayed.

This command displays information for each of the currently configured instances. The instance number, local port, and address information are displayed. The instance state is either available or deletion pending. An instance enters the deletion pending state when a request is made to delete it but there are currently established associations for that instance. The instance cannot be deleted immediately and instead enters the pending state. No new associations are allowed in this instance, and when the last association is terminated or fails, the instance is deleted.
The default inbound and outbound stream numbers are used for establishing incoming associations, and the maximum number of associations allowed for this instance is shown. Then a snapshot of each existing association is shown, if any exists.
Effective with Cisco IOS Release 12.4(11)T, if you enter the show ip sctp instances command, you must type the complete word instances in the command syntax.
The following sample output shows available IP SCTP instances. In this example, two current instances are active and available. The first is using local port 8989, and the second is using 9191. Instance identifier 0 has three current associations, and instance identifier 1 has no current associations.
Router# show ip sctp instances *** SCTP Instances **** Instance ID:0 Local port:8989 Instance state:available Local addrs:10.1.0.2 10.2.0.2 Default streams inbound:1 outbound:1 Current associations: (max allowed:6) AssocID:0 State:ESTABLISHED Remote port:8989 Dest addrs:10.6.0.4 10.5.0.4 AssocID:1 State:ESTABLISHED Remote port:8990 Dest addrs:10.6.0.4 10.5.0.4 AssocID:2 State:ESTABLISHED Remote port:8991 Dest addrs:10.6.0.4 10.5.0.4 Instance ID:1 Local port:9191 Instance state:available Local addrs:10.1.0.2 10.2.0.2 Default streams inbound:1 outbound:1 No current associations established for this instance.

This command displays the overall SCTP statistics accumulated since the last clear ip sctp statistics command. It includes numbers for all currently established associations, and for any that have been terminated. The statistics indicated are similar to those shown for individual associations.
The following sample output shows IP SCTP statistics:
