Table 2-48 describes the fields shown in the displays.

Table 2-48 show ip igmp groups Field Descriptions 

Field
Description

Group Address

Address of the multicast group.

Interface

Interface through which the group is reachable.

Uptime

Time in weeks, days, hours, minutes, and seconds that this multicast group has been known.

Expires

Time in weeks, days, hours, minutes, and seconds until the entry expires. If an entry expires, then the entry (for a short period) shows "now" before it is removed.

"never" indicates that the entry will not time out, because a local receiver is on this router for this entry.

"stopped" indicates that timing out of this entry is not determined by this expire timer. If the router is in INCLUDE mode for a group, then the whole group entry times out after the last source entry has timed out (unless the mode is changed to EXCLUDE mode before it times out).

Last Reporter

Last host to report being a member of the multicast group. Both IGMP v3lite and URD require a v2-report.

Group mode:

Either INCLUDE or EXCLUDE. The group mode is based on the type of membership reports that are received on the interface for the group. In the output for the show ip igmp groups detail command, the EXCLUDE mode also shows the Expires: field for the group entry (not shown in the output).

CSR Grp Exp

Shown for multicast groups in the SSM range. It indicates the time (in hours, minutes, and seconds) since the last received group membership report was received. Cisco IOS software needs to use these reports for the operation of URD and IGMP v3lite, but the reports do not indicate group membership by themselves.

Group source list:

Details of which sources have been requested by the multicast group.

Source Address

IP address of the source.

Uptime

Time since the source state was created.

v3 Exp

Time in hours, minutes, and seconds until the membership for the source times out according to IGMP operations. "stopped" displays if no member uses IGMPv3 (but only IGMP v3lite or URD).

CSR Exp

Time in hours, minutes, and seconds until the membership for the source times out according to IGMP v3lite or URD reports. "stopped" displays if members use only IGMPv3.

Fwd

Status of whether the router is forwarding multicast traffic due to this entry.

Flags

Information about the entry. The Remote flag indicates that an IGMPv3 report has been received by this source. The C flag indicates that an IGMP v3lite or URD report was received by this source. The U flag indicates that a URD report was received for this source.

Support for this command was introduced.


Usage Guidelines

This command displays which groups are being forwarded and received over the UDL.

On the upstream router, this command shows which interface is a UDL interface and which IP multicast groups are being forwarded out that interface. The UDL Reporter is the IP address of the downstream interface on the receiving router. If there is more than one downstream router, this field shows which downstream router forwarded the IGMP host report to the upstream router over the ground-based network. This report is forwarded over the UDL so that all downstream routers know which groups have already been requested by other downstream routers, and additional IGMP host reports are suppressed.

On the downstream router, this command (in the Interface field) shows which local interface received an IGMP host report (from a connected host for a specific group). The UDL Reporter is the IP address of the router that had forwarded the IGMP host report to the upstream router over the ground-based network. The UDL Interfaces column shows the interface on which IP multicast packets are being received.

Examples

This example shows the output of the show ip igmp udlr command on an upstream router:

Router# show ip igmp udlr
 
   
IGMP UDLR Status, UDL Interfaces: Serial0
Group Address    Interface            UDL Reporter     Reporter Expires

Support for this command was introduced.


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 only information 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.

Examples

This example shows how to display the usability status for a specific VLAN:

Modification

12.2(18)ZY

Support for this command was introduced.


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 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.

The port-channel number values are from 257 to 282 are supported on the CSM and the FWSM only.

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 that is found in the unicast routing table (through RPF).

Table 2-55 describes the fields that are shown in the example.

Table 2-55 show ip mroute Field Descriptions 

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

Router 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 whether the (S,G) entry is pointing toward the route processor. This field shows a prune state along the shared tree for a particular source.

F - Register flag

Status of whether the software is registering for a multicast source.

T - SPT-bit set

Status of whether the packets have been received on the shortest-path tree.

J - Join SPT

For (*, G) entries, indicates that the rate of traffic flowing down the shared tree is exceeding the SPT-Threshold that is 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 that is received down the shared tree triggers an (S,G) join in the direction of the source causing the router 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 router 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 1 minute.

The router 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 router immediately switches to the shortest-path tree when traffic from a new source is received.

Bidir-Upstream: Null, RPF nbr 0.0.0.0, RPF-MFD

Interface that is used to reach the PIM route processor. Set to Null if the router is the PIM route processor or if no route exists to the PIM route processor.

Outgoing interface flags:

Information about the outgoing entry.

H - Hardware switched

Entry is hardware switched.

Timers:

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 router followed by the IP address of the multicast group. An asterisk (*) in place of the source router 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

Hours, minutes, and seconds that the entry has been in the IP-multicast routing table.

expires

Hours, minutes, and seconds until the entry is removed from the IP-multicast routing table on the outgoing interface.

RP

Address of the route processor. For routers 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 router to the source. Tunneling indicates that this router is sending data that is encapsulated in register packets to the route processor. The hexadecimal number in parentheses indicates to which route processor it is registering. Each bit indicates a different route processor if multiple route processors per group are used.

Dvmrp or Mroute

Status of whether the RPF information is obtained from the DVMRP routing table or the static mroute configuration.

Outgoing interface list:

Interfaces through which packets are forwarded. When you enable the ip pim nbma-mode command 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 the 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 whether the packets are forwarded on the interface if there are no restrictions due to access lists or the TTL threshold. Following the slash (/), the 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, the duration in hours, minutes, and seconds that the entry has been in the IP-multicast routing table. Specifies that following the slash (/), the duration in hours, minutes, and seconds until the entry is removed from the IP-multicast routing table.

Usage Guidelines

Use the show ipv6 mfib command to display MFIB entries, forwarding interfaces, and their traffic statistics. This command can be enabled on virtual IP (VIP) if the router is operating in distributed mode.

Use the show ipv6 mfib active command to display MFIB entries actively used to forward packets. In many cases, it is useful to provide the optional kbps argument to display the set of entries that are forwarding an amount of traffic larger or equal to the amount set by the kbps argument.

Use the show ipv6 mfib count command to display the average packet size and data rate in kilobits per seconds.

The prefix-length is the length of the IPv6 prefix. A decimal value that indicates how many of the high-order contiguous bits of the address comprise the prefix (the network portion of the address). A slash mark must precede the decimal value.

A forwarding entry in the MFIB has flags that determine the default forwarding and signaling behavior to use for packets matching the entry. The entry also has per-interface flags that further specify the forwarding behavior for packets received or forwarded on specific interfaces. Table 2-71 describes the MFIB forwarding entries and interface flags.

Table 2-71 MFIB Forwarding Entries and Interface Flags

Flag
Description

F

Forward—Data is forwarded out of this interface.

A

Accept—Data received on this interface is accepted for forwarding.

IC

Internal copy—Deliver a copy of the packets received or forwarded on this interface to the router.

NS

Negate signal—Reverse the default entry signaling behavior for packets received on this interface.

DP

Do not preserve—When signaling the reception of a packet on this interface, do not preserve a copy of it (discard it instead).

SP

Signal present—The reception of a packet on this interface was just signaled.

S

Signal—By default, signal the reception of packets matching this entry.

C

Perform directly connected check for packets matching this entry. Signal the reception if packets were originated by a directly connected source.

Field
Description

Group:

Summary information about counters for (*, G) and the range of (S,G) states for one particular group G. The following RP-tree: and Source: output fields contain information about the individual states belonging to this group.

Note For PIM-SSM range groups, the Group: displays are statistical. All SSM range (S,G) states are individual, unrelated SSM channels.

Rate...kbps

Bytes per second divided by packets per second and divided by 1000. On an IP multicast fast-switching platform, the number of packets per second is the number of packets during the last second. Other platforms may use a different approach to calculate this number. Refer to the Catalyst Supervisor Engine 32 PISA Cisco IOS Software Configuration Guide—Release 12.2ZY for more information.

Table 2-74 describes the fields shown in the display.

Table 2-74 show ipv6 mfib count Field Descriptions 

Field
Description

Forwarding Counts

Statistics on the packets that are received and forwarded to at least one interface.

Pkt Count/

Total number of packets received and forwarded since the multicast forwarding state to which this counter applies was created.

Pkts per second/

Number of packets received and forwarded per second.

Avg Pkt Size/

Total number of bytes divided by the total number of packets for this multicast forwarding state. There is no direct display for the total number of bytes. You can calculate the total number of bytes by multiplying the average packet size by the packet count.

Kilobits per second

Bytes per second, divided by packets per second, and divided by 1000.

Other counts:

Statistics on the received packets. These counters include statistics about the packets received and forwarded and packets received but not forwarded.

Total/

Total number of packets received.

RPF failed/

Number of packets not forwarded due to a failed RPF or acceptance check (when bidirectional PIM is configured).

Other drops (OIF-null, rate-limit etc)

Number of packets not forwarded for reasons other than an RPF or acceptance check (such as the outgoing interface [OIF] list was empty or because the packets were discarded because of a configuration that was enabled).

Group:

Summary information about counters for (*,G) and the range of (S,G) states for one particular group G. The following RP-tree: and Source: output fields contain information about the individual states belonging to this group.

Note For Source Specific Multicast (PIM-SSM) range groups, the Group: displays are statistical. All SSM range (S,G) states are individual, unrelated SSM channels.

RP-tree:

Counters for the (*,G) state of this group G. These counters are displayed only for groups that have a forwarding mode that do not forward packets on the shared tree. These (*,G) groups are bidirectional PIM and PIM sparse mode (PIM-SM) groups. There are no RP-tree displays for PIM SSM range groups.

Usage Guidelines

If you do not specify a module number, the output of the show mac-address-table command displays information about the supervisor engine. To display information about the MAC-address table of the switch processor, you must enter the all keyword.

The mac-addr is a 48-bit MAC address and the valid format is H.H.H.

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.

Valid values for mac-group-address are from 1 to 9.

The optional count keyword displays the number of multicast entries.

The optional multicast keyword displays the multicast MAC addresses (groups) in a VLAN or displays all statically installed or IGMP snooping-learned entries in the Layer 2 table.

The information that is displayed in the show mac-address-table unicast-flood command output is as follows:

Up to 50 flood entries, shared across all the VLANs that are not configured to use the filter mode, can be recorded.

The output field displays are defined as follows:

ALERT—Information is updated approximately every 3 seconds.

SHUTDOWN—Information is updated approximately every 3 seconds.


Note The information displayed on the destination MAC addresses is deleted as soon as the floods stop after the port shuts down.


Information is updated each time that you install the filter. The information lasts until you remove the filter.

The show mac-address-table protocol {assigned | ip | ipx | other} syntax is not supported on Catalyst 6500 series switches that are configured with a Supervisor Engine 720.

The keyword definitions for the protocol argument are as follows:

assigned specifies assigned protocol entries.

ip specifies IP protocol.

ipx specifies IPX protocols.

other specifies other protocol entries.

The dynamic entries that are displayed in the Learn field are always set to Yes.

The show mac-address-table limit command output displays the following information:

The current number of MAC addresses.

The maximum number of MAC entries that are allowed.

The percentage of usage.

The show mac-address-table synchronize statistics command output displays the following information:

Number of messages processed at each time interval.

Number of active entries sent for synchronization.

Number of entries updated, created, ignored, or failed.
