show interfaces rep
To display Resilient Ethernet Protocol (REP) configuration and status for a specified interface or for all interfaces, use the show interfaces rep command in EXEC mode.

Syntax Description
(Optional) A specified physical interface or port channel ID. |
|
(Optional) Displays detailed REP configuration and status information. |
Defaults
Command Modes
Command History
|
|
|
|---|---|
Usage Guidelines
In the output for the show interface rep [ detail ] command, in addition to an Open, Fail, or AP (alternate port) state, the Port Role might show as Fail Logical Open (FailLogOpen) or Fail No Ext Neighbor (FailNoNbr). These states indicate that the port is physically up, but REP is not configured on the neighboring port. In this case, one port goes into a forwarding state for the data path to help maintain connectivity during configuration. The Port Role for this port shows as Fail Logical Open; the port forwards all data traffic on all VLANs. The other failed Port Role shows as Fail No Ext Neighbor; this port blocks traffic for all VLANs.
When the external neighbors for the failed ports are configured, the failed ports go through the alternate port state transitions and eventually go to an Open state or remain as the alternate port, based on the alternate port election mechanism.
In the show interfaces rep command output, ports configured as edge no-neighbors are designated with an asterisk (*) in front of Primary Edge or Secondary Edge. In the output of the show interfaces rep detail command, No-Neighbor is spelled out.
The output of this command is also included in the show tech-support privileged EXEC command output.

A -- in the display appears in place of all data except the packet count and the time. No other statistics are provided for the entry. If you see this entry in the display, increase the number of entries in the log buffer, or increase the logging rate in the ip arp inspection log-buffer global configuration command.
This is an example of output from the show ip arp inspection statistics command. It shows the statistics for packets that have been processed by dynamic ARP inspection for all active VLANs:
For the show ip arp inspection statistics command, the switch increments the number of forwarded packets for each ARP request and response packet on a trusted dynamic ARP inspection port. The switch increments the number of ACL or DHCP permitted packets for each packet that is denied by source MAC, destination MAC, or IP validation checks, and the switch increments the appropriate failure count.
This is an example of output from the show ip arp inspection statistics vlan 5 command. It shows statistics for packets that have been processed by dynamic ARP for VLAN 5:

- On the Gigabit Ethernet 4 interface, IP source guard with source IP and MAC address filtering is enabled, and static IP source bindings are configured on VLANs 10 and 11. For VLANs 12 to 20, the default port ACL is applied on the interface for the VLANs on which IP source guard is not configured.
- On the Gigabit Ethernet 5 interface, IP source guard with source IP and MAC address filtering is enabled and configured with a static IP binding, but port security is disabled. The switch cannot filter source MAC addresses.

show ipv6 dhcp conflict
To display address conflicts found by a Dynamic Host Configuration Protocol for IPv6 (DHCPv6) server when addresses are offered to the client, use the show ipv6 dhcp conflict command in Privileged EXEC mode.
Note This command is available only if you have configured a dual IPv4 and IPv6 Switch Database Management (SDM) template on the switch and the switch is running the IP services image.
Syntax Description

|
|---|---|
Usage Guidelines
To configure the dual IPv4 and IPv6 template, enter the sdm prefer dual-ipv4-and-ipv6 global configuration command, and reload the switch.
When you configure the DHCPv6 server to detect conflicts, it uses ping. The client uses neighbor discovery to detect clients and reports to the server through a DECLINE message. If an address conflict is detected, the address is removed from the pool, and the address is not assigned until the administrator removes the address from the conflict list.
Examples
This is an example of the output from the show ipv6 dhcp conflict command:

Command History
|
|
|
|---|---|
Usage Guidelines
Use the show ipv6 mld snooping querier command to display the MLD version and IPv6 address of a detected device that sends MLD query messages, which is also called a querier. A subnet can have multiple multicast routers but has only one MLD querier. The querier can be a Layer 3 switch.
The show ipv6 mld snooping querier command output also shows the VLAN and interface on which the querier was detected. If the querier is the switch, the output shows the Port field as Router. If the querier is a router, the output shows the port number on which the querier is learned in the Port field.
The output of the show ipv6 mld snoop querier vlan command displays the information received in response to a query message from an external or internal querier. It does not display user-configured VLAN values, such as the snooping robustness variable on the particular VLAN. This querier information is used only on the MASQ message that is sent by the switch. It does not override the user-configured robustness variable that is used for aging out a member that does not respond to query messages.
VLAN numbers 1002 through 1005 are reserved for Token Ring and FDDI VLANs and cannot be used in MLD snooping.
To configure the dual IPv4 and IPv6 template, enter the sdm prefer dual-ipv4-and-ipv6 global configuration command and reload the switch.
Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output do not appear, but the lines that contain Output appear.

show mls qos maps
To display quality of service (QoS) mapping information, use the show mls qos maps command in EXEC mode. During classification, QoS uses the mapping tables to represent the priority of the traffic and to derive a corresponding class of service (CoS) or Differentiated Services Code Point (DSCP) value from the received CoS, DSCP, or IP precedence value.
show mls qos maps [ cos-dscp | cos-input-q | cos-output-q | dscp-cos | dscp-input-q | dscp-mutation dscp-mutation-name | dscp-output-q | ip-prec-dscp | policed-dscp ]
Note This command is available only when the switch is running the LAN Base image.
Syntax Description
(Optional) Displays the specified DSCP-to-DSCP-mutation map. |

The policed-DSCP, DSCP-to-CoS, and the DSCP-to-DSCP-mutation maps appear as a matrix. The d1 column specifies the most-significant digit in the DSCP. The d2 row specifies the least-significant digit in the DSCP. The intersection of the d1 and d2 values provides the policed-DSCP, the CoS, or the mutated-DSCP value. For example, in the DSCP-to-CoS map, a DSCP value of 43 corresponds to a CoS value of 5.
The DSCP input queue threshold and the DSCP output queue threshold maps appear as a matrix. The d1 column specifies the most-significant digit of the DSCP number. The d2 row specifies the least-significant digit in the DSCP number. The intersection of the d1 and the d2 values provides the queue ID and threshold ID. For example, in the DSCP input queue threshold map, a DSCP value of 43 corresponds to queue 2 and threshold 1 (02-01).
The CoS input queue threshold and the CoS output queue threshold maps show the CoS value in the top row and the corresponding queue ID and threshold ID in the second row. For example, in the CoS input queue threshold map, a CoS value of 5 corresponds to queue 2 and threshold 1 (2-1).
