The interface-number argument designates the module and port number. Valid values for interface-number depend on the specified interface type and the chassis and module that are used. For example, if you specify a Gigabit Ethernet interface and have a 48-port 10/100BASE-T Ethernet module that is installed in a 13-slot chassis, valid values for the module number are from 1 to 13, and valid values for the port number are from 1 to 48.
Hardware Layer 3 switching adjacency statistics are updated every 60 seconds.
The following information is contained in the show adjacency command:
•
Protocol interface.
•
Type of routing protocol that is configured on the interface.
•
Interface address.
•
Method of adjacency that was learned.
•
MAC address of the adjacent router.

12.2(40)SG |
Support for WS-X4606-10GE-E Twin Gigabit convertor introduced. |
Usage Guidelines
When a TwinGig Convertor is enabled or disabled, the number and type of ports on the linecard change dynamically. The terminology must reflect this behavior. In Cisco IOS, 10-Gigabit ports are named TenGigabit and 1-Gigabit ports are named Gigabit. Starting with Cisco IOS Release 12.2(40)SG, to avoid having ports named TenGigabit1/1 and Gigabit1/1, the 10-Gigabit and 1-Gigabit port numbers are independent. The WS-X4606-10GE-E module with six X2 ports are named TenGigabit<slot-num>/<1-6>, and the SFP ports are named Gigabit<slot-num>/<7-18.
In the Supervisor Engine 6-E and Catalyst 4900M chassis, the ports are connected to the switching engine through a stub ASIC. This stub ASIC imposes some limitations on the ports: Gigabit and 10-Gigabit ports cannot be mixed on a single stub ASIC; they must either be all 10-Gigabit (X2), or all Gigabit (TwinGig Converter and SFP). The faceplates of X2 modules show this stub-port grouping, either with an actual physical grouping, or a box drawn around a grouping.
Examples
This example shows to determine how the X2 holes on a module are grouped on a WS-X4606-10GE-E:
Switch# show hw-module module 1 port-group
Module Port-group Active Inactive

Usage Guidelines
The statistics are collected per VLAN for Layer 2 switched packets and Layer 3 switched packets. The statistics are available for both unicast and multicast. The Layer 3 switched packet counts are available for both the ingress and egress directions. The per-VLAN statistics are updated every 5 seconds.
In some cases, the duplex mode that is displayed by the show interfaces command is different than that displayed by the show running-config command. The duplex mode that is displayed in the show interfaces command is the actual duplex mode that the interface is running. The show interfaces command shows the operating mode for an interface, but the show running-config command shows the configured mode for an interface.
If you do not enter any keywords, all counters for all modules are displayed.
Linecards that support auto-MDIX configuration on their copper media ports include: WS-X4124-RJ45, WS-X4148-RJ with hardware revision 3.0 or later, and WS-X4232-GB-RJ with hardware revision 3.0 or later.

show interfaces transceiver
To display diagnostic-monitoring data for all interfaces that have transceivers installed, use the show interfaces transceiver command.
show interfaces {{[int_name] transceiver {[detail]} | {transceiver [module mod] | detail [module mod]}}
Syntax Description
int_name |
(Optional) Interface. |
detail |
(Optional) Displays the calibrated values and the A2D readouts if the readout values differ from the calibrated values. Also displays the high-alarm, high-warning, low-warning, and low-alarm thresholds. |
module mod |
(Optional) Limits the display to interfaces on a specific module. |
Defaults
The noninterface-specific versions of the show interfaces transceiver command are enabled by default.
The interface-specific versions of these commands are enabled by default if the specified interface has a transceiver (GBIC or SFP) that is configured for diagnostic monitoring, and the transceiver is in a module that supports diagnostic monitoring.
Command Modes
Privileged EXEC mode
Command History
|
|
12.1(20)EW |
Support for this command was introduced on the Catalyst 4500 series switch. |
12.2(18)EW |
Support for the calibration keyword was withdrawn. |
Usage Guidelines
The show interfaces transceiver command provides useful information under the following conditions:
•
At least one transceiver is installed on a chassis that is configured for diagnostic monitoring.
•
The transceiver is in a module that supports diagnostic monitoring.
If you notice that the alarm and warning flags have been set on a transceiver, reenter the command to confirm.
Examples
This example shows how to display diagnostic monitoring data for all interfaces with transceivers installed on the switch:
Switch# show interfaces transceiver
If device is externally calibrated, only calibrated values are printed.
++ : high alarm, + : high warning, - : low warning, -- : low alarm.
NA or N/A: not applicable, Tx: transmit, Rx: receive.
mA: milliamperes, dBm: decibels (milliwatts).
Temperature Voltage Current Tx Power Rx Power
Port (Celsius) (Volts) (mA) (dBm) (dBm)
------- ----------- ------- -------- -------- --------

Gi2/1 43.7 5.03 50.6 + -16.7 -- N/A
Gi2/2 39.2 5.02 25.7 0.8 N/A
Note
The value for the Optical Tx Power (in dBm) equals ten times log (Tx Power in mW). If the Tx Power value is 3 mW, then the Optical Tx Power value equals 10 * log (3), which equals 10 * .477 or 4.77 dBm. The Optical Rx Power value behaves similarly. If the Tx Power or the Rx Power is zero, then its dBm value is undefined and is shown as N/A (not applicable).
This example shows how to display detailed diagnostic monitoring data, including calibrated values, alarm and warning thresholds, A2D readouts, and alarm and warning flags. The A2D readouts are reported separately in parentheses only if they differ from the calibrated values:

12.2(25)EW |
Extended to include the 10-Gigabit Ethernet interface. |
Usage Guidelines
The Cisco IOS software automatically enters a directly connected route in the routing table if the interface is usable. A usable interface is one through which the software can send and receive packets. If the software determines that an interface is not usable, it removes the directly connected routing entry from the routing table. Removing the entry allows the software to use dynamic routing protocols to determine backup routes to the network, if any.
If the interface can provide two-way communication, the line protocol is marked "up." If the interface hardware is usable, the interface is marked "up."
If you specify an optional interface type, you see information only on that specific interface.
If you specify no optional arguments, you see information on all the interfaces.
When an asynchronous interface is encapsulated with PPP or Serial Line Internet Protocol (SLIP), IP fast switching is enabled. The show ip interface command on an asynchronous interface that is encapsulated with PPP or SLIP displays a message indicating that IP fast switching is enabled.

Support for this command was introduced on the Catalyst 4500 series switch. |
12.2(40)SG |
Support for command introduced on the Supervisor Engine 6-E and Catalyst 4900M chassis. |
Usage Guidelines
In the Supervisor Engine 6-E and Catalyst 4900M chassis, the output of the show ip mfib command does not display any hardware counters.
The MFIB table contains a set of IP multicast routes; each route in the MFIB table contains several flags that associate to the route.
The route flags indicate how a packet that matches a route is forwarded. For example, the IC flag on an MFIB route indicates that some process on the switch needs to receive a copy of the packet. These flags are associated with MFIB routes:
•
Internal Copy (IC) flag—Set on a route when a process on the switch needs to receive a copy of all packets matching the specified route.
•
Signaling (S) flag—Set on a route when a switch process needs notification that a packet matching the route is received. In the expected behavior, the protocol code updates the MFIB state in response to having received a packet on a signaling interface.
•
Connected (C) flag—When set on a route, the C flag has the same meaning as the S flag, except that the C flag indicates that only packets sent by directly connected hosts to the route should be signaled to a protocol process.
A route can also have a set of flags associated with one or more interfaces. For an (S,G) route, the flags on interface 1 indicate how the ingress packets should be treated and whether packets matching the route should be forwarded onto interface 1. These per-interface flags are associated with the MFIB routes:
•
Accepting (A)—Set on the RPF interface when a packet that arrives on the interface and that is marked as Accepting (A) is forwarded to all Forwarding (F) interfaces.
•
Forwarding (F)—Used with the A flag as described above. The set of forwarding interfaces together form a multicast olist or output interface list.
•
Signaling (S)—Set on an interface when a multicast routing protocol process in Cisco IOS needs to be notified of ingress packets on that interface.
•
Not Platform (NP) fast-switched—Used with the F flag. A forwarding interface is also marked as Not Platform fast-switched whenever that output interface cannot be fast-switched by the platform hardware and requires software forwarding.
For example, the Catalyst 4506 switch with Supervisor Engine III cannot switch tunnel interfaces in hardware so these interfaces are marked with the NP flag. When an NP interface is associated with a route, a copy of every ingress packet arriving on an Accepting interface is sent to the switch software forwarding path for software replication and then forwarded to the NP interface.

Support for this command was introduced on the Catalyst 4500 series switch. |
12.2(25)EW |
Added support for the 10-Gigabit Ethernet interface. |
Usage Guidelines
If you omit all the optional arguments and keywords, the show ip mroute command displays all the entries in the IP multicast routing table.
The show ip mroute active kbps command displays all the sources sending at a rate greater than or equal to kbps.
The multicast routing table is populated by creating source, group (S,G) entries from star, group (*,G) entries. The star refers to all source addresses, the "S" refers to a single source address, and the "G" refers to the destination multicast group address. In creating (S,G) entries, the software uses the best path to that destination group found in the unicast routing table (through Reverse Path Forwarding (RPF).

Table 2-20 show ip mroute Field Descriptions
|
|
Flags: |
Information about the entry. |
D - Dense |
Entry is operating in dense mode. |
S - Sparse |
Entry is operating in sparse mode. |
s - SSM Group |
Entry is a member of an SSM group. |
C - Connected |
Member of the multicast group is present on the directly connected interface. |
L - Local |
Switch is a member of the multicast group. |
P - Pruned |
Route has been pruned. This information is retained in case a downstream member wants to join the source. |
R - Rp-bit set |
Status of the (S,G) entry; is the (S,G) entry pointing toward the RP. The R - Rp-bit set is typically a prune state along the shared tree for a particular source. |
F - Register flag |
Status of the software; indicates if the software is registered for a multicast source. |
T - SPT-bit set |
Status of the packets; indicates if the packets been received on the shortest path source tree. |
J - Join SPT |
For (*, G) entries, indicates that the rate of traffic flowing down the shared tree is exceeding the SPT-Threshold set for the group. (The default SPT-Threshold setting is 0 kbps.) When the J - Join SPT flag is set, the next (S,G) packet received down the shared tree triggers an (S,G) join in the direction of the source causing the switch to join the source tree. For (S, G) entries, indicates that the entry was created because the SPT-Threshold for the group was exceeded. When the J - Join SPT flag is set for (S,G) entries, the switch monitors the traffic rate on the source tree and attempts to switch back to the shared tree for this source if the traffic rate on the source tree falls below the group's SPT-Threshold for more than one minute. The switch measures the traffic rate on the shared tree and compares the measured rate to the group's SPT-Threshold once every second. If the traffic rate exceeds the SPT-Threshold, the J- Join SPT flag is set on the (*, G) entry until the next measurement of the traffic rate. The flag is cleared when the next packet arrives on the shared tree and a new measurement interval is started. If the default SPT-Threshold value of 0 Kbps is used for the group, the J- Join SPT flag is always set on (*, G) entries and is never cleared. When the default SPT-Threshold value is used, the switch immediately switches to the shortest-path tree when traffic from a new source is received. |
Outgoing interface flag: |
Information about the outgoing entry. |
H - Hardware switched |
Entry is hardware switched. |
Timer: |
Uptime/Expires. |
Interface state: |
Interface, Next-Hop or VCD, State/Mode. |
(*, 224.0.255.1) (198.92.37.100/32, 224.0.255.1) |
Entry in the IP multicast routing table. The entry consists of the IP address of the source switch followed by the IP address of the multicast group. An asterisk (*) in place of the source switch indicates all sources. Entries in the first format are referred to as (*,G) or "star comma G" entries. Entries in the second format are referred to as (S,G) or "S comma G" entries. (*,G) entries are used to build (S,G) entries. |
uptime |
How long (in hours, minutes, and seconds) the entry has been in the IP multicast routing table. |
expires |
How long (in hours, minutes, and seconds) until the entry is removed from the IP multicast routing table on the outgoing interface. |
RP |
Address of the RP switch. For switches and access servers operating in sparse mode, this address is always 0.0.0.0. |
flags: |
Information about the entry. |
Incoming interface |
Expected interface for a multicast packet from the source. If the packet is not received on this interface, it is discarded. |
RPF neighbor |
IP address of the upstream switch to the source. "Tunneling" indicates that this switch is sending data to the RP encapsulated in Register packets. The hexadecimal number in parentheses indicates to which RP it is registering. Each bit indicates a different RP if multiple RPs per group are used. |
DVMRP or Mroute |
Status of whether the RPF information is obtained from the DVMRP routing table or the static mroutes configuration. |
Outgoing interface list |
Interfaces through which packets are forwarded. When the ip pim nbma-mode command is enabled on the interface, the IP address of the PIM neighbor is also displayed. |
Ethernet0 |
Name and number of the outgoing interface. |
Next hop or VCD |
Next hop specifies downstream neighbor's IP address. VCD specifies the virtual circuit descriptor number. VCD0 indicates that the group is using the static-map virtual circuit. |
Forward/Dense |
Status of the packets; indicates if they are they forwarded on the interface if there are no restrictions due to access lists or the TTL threshold. Following the slash (/), mode in which the interface is operating (dense or sparse). |
Forward/Sparse |
Sparse mode interface is in forward mode. |
time/time (uptime/expiration time) |
Per interface, how long (in hours, minutes, and seconds) the entry has been in the IP multicast routing table. Following the slash (/), how long (in hours, minutes, and seconds) until the entry is removed from the IP multicast routing table. |

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 switches 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.

This command was introduced on the Catalyst 4500 series switch. |
Usage Guidelines
Before attempting an ISSU, you should know the compatibility level between the old and the new Cisco IOS software versions on the active and the standby-supervisor engines. ISSU will not work if the two versions are incompatible.
The compatibility matrix is available on Cisco.com so that you can also veiw in advance whether an upgrade can be performed with the ISSU process. The compatibility matrix during the ISSU process and later by entering the show issu comp-matrix command. To display information on the negotiation of the compatibility matrix data between two software versions on a given system, use the show issu comp-matrix negotiated command.
Compatibility matrix data is stored with each Cisco IOS software image that supports ISSU capability. To display stored compatibility matrix information, use the show issu comp-matrix stored command.
The compatibility matrix information are built-in any IOS ISSU image. The ISSU infrastructure performs a matrix lookup as soon as the communication with the standby supervisor engine is established. There are three possible results from the lookup operation:
•
Compatible—The Base-level system infrastructure and all optional HA-aware subsystems are compatible. In-service upgrade or downgrade between these versions will succeed with minimal service impact.
•
Base-Level Compatible—One or more of the optional HA-aware subsystems are not compatible. Although an in-service upgrade or downgrade between these versions will succeed, some subsystems will not be able to maintain their state during the switchover. Prior to attempting an in-service upgrade or downgrade, the impact of this on operation and service of the switch must be considered carefully.
•
Incompatible—A set of core system infrastructure must be able to execute in a stateful manner for SSO to function correctly. If any of these "required" features or subsystems is not compatible in two different IOS images, the two versions of the Cisco IOS images are declared "Incompatible". This means that an in-service upgrade or downgrade between these versions is not possible. The systems operates in RPR mode during the period when the versions of IOS at the active and standby supervisor engines differ.

12.2(31)SGA |
This command was introduced on the Catalyst 4500 series switch. |
Usage Guidelines
Session is bidirectional and a reliable connection is established between two endpoints. Sync-data and negotiation messages are sent to the peer endpoint through a session. On a Catalyst 4500 series switch, each ISSU-aware client has a maximum of one session at each endpoint.
When an ISSU-aware client establishes its session with the peer, an ISSU negotiation takes place. The ISSU infrastructure uses the registered information to negotiate the capabilities and the message version to be used during the session.
Examples
The following example shows how to display the rollback-timer status:
Switch#show issu sessions 2072
