12.1(12c)EW

Support for this command was introduced on the Catalyst 4500 series switch.


Usage Guidelines

If you do not specify an interface, global parameters and a summary are displayed. If you specify an interface, details for that interface are displayed.

If you specify the statistics keyword without the interface interface-id option, statistics are displayed for all interfaces. If you specify the statistics keyword with the interface interface-id option, statistics are displayed for the specified interface.

Expressions are case sensitive. For example, if you enter | exclude output, the lines that contain output are not displayed, but the lines that contain Output are displayed.

Examples

This is an example of output from the show dot1x privileged EXEC command:

Switch# show dot1x
Sysauthcontrol						= Disabled
Dot1x Protocol Version				= 1
Dot1x Oper Controlled Directions		= Both
Dot1x Admin Controlled Directions	= Both
Switch#

This is an example of output from the show dot1x interface gigabitethernet1/1 privileged EXEC command. Table 2-12 describes the fields in the display.

Switch# show dot1x interface g1/1

Default Dot1x Configuration Exists for this interface GigabitEthernet1/1
AuthSM State      = FORCE AUTHORIZED
BendSM State      = IDLE
PortStatus        = AUTHORIZED
MaxReq            = 2 
MultiHosts        = Disabled 
PortControl       = Force Authorized
QuietPeriod       = 60 Seconds 
Re-authentication = Disabled 
ReAuthPeriod      = 3600 Seconds
ServerTimeout     = 30 Seconds 
SuppTimeout       = 30 Seconds 
TxPeriod          = 30 Seconds 
Switch#

The "Default Dot1x Configuration Exists" line goes away if the config on the interface is non-default. The "Show dot1x all" output is repeated in the show dot1x interface command output for all interfaces with non-default dot1x configurations.

Table 2-12 show dot1x interface Field Description 

Field
Description

802.1X is enabled on GigabitEthernet0/2

 

Status

Status of the port (authorized or unauthorized). The status of a port is displayed as authorized if the dot1x port-control interface configuration command is set to auto and has successfully completed authentication.

Port-control

Setting of the dot1x port-control interface configuration command.

Supplicant

Ethernet MAC address of the client, if one exists. If the switch has not discovered the client, this field displays Not set.

Multiple Hosts

Setting of the dot1x multiple-hosts interface configuration command (allowed or disallowed).

Current Identifier1

Each exchange between the switch and the client includes an identifier, which matches requests with responses. This number is incremented with each exchange and can be reset by the authentication server.

1 This field and the remaining fields in the display show internal state information. For a detailed description of these state machines and their settings, refer to the IEEE 802.1X specification.

show interfaces

To display traffic on a specific interface, use the show interfaces command.

show interfaces [{{FastEthernet mod/interface-number} | {GigabitEthernet mod/interface-number} | {Null interface-number} | Vlan vlan_id} | status}]

Syntax Description

FastEthernet mod/interface-number

(Optional) Specifies the Fast Ethernet module and interface.

GigabitEthernet mod/interface-number

(Optional) Specifies the Gigabit Ethernet module and interface.

Null interface-number

(Optional) Specifies the null interface; the valid value is 0.

Vlan vlan_id

(Optional) Specifies the VLAN; valid values are from 1 to 4094.

status

(Optional) Displays status information.

Modification

12.1(8a)EW

Support for this command was introduced on the Catalyst 4500 series switch.

12.1(12c)EW

Support for extended VLAN addresses was added.


Usage Guidelines

Statistics are collected on a per-VLAN basis for Layer 2-switched packets and Layer 3-switched packets. Statistics are available for both unicast and multicast. The Layer 3-switched packet counts are available for both ingress and egress directions. The per-VLAN statistics are updated every 5 seconds.

In some cases, you might see a difference in the duplex mode displayed between the show interfaces command and the show running-config commands. The duplex mode displayed in the show interfaces command is the actual duplex mode the interface is running. The show interfaces command shows the operating mode for an interface, while 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.

Modification

12.1(8a)EW

Support for this command was introduced on the Catalyst 4500 series switch.


Usage Guidelines

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. The following 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 ingress packets should be treated and whether packets matching the route should be forwarded onto interface 1.

The following per-interface flags are associated with 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 in conjunction 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 IOS needs to be notified of ingress packets on that interface.

Not Platform (NP) fast-switched—Used in conjunction 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 4006 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.

Usage Guidelines

If you omit all optional arguments and keywords, the show ip mroute command displays all entries in the IP multicast routing table.

The show ip mroute active kbps command displays all 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" is 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 (that is, through Reverse Path Forwarding (RPF).

Field
Description

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 itself 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; is the software registered for a multicast source.

T - SPT-bit set

Status of the packets; have 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

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 means the group is using the static-map virtual circuit.

Forward/Dense

Status of the packets; 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.
