Monitoring Ssm Mapping - Cisco 3845 - Security Bundle Router Software Manual

Chapter 33 Configuring IP Multicast Routing
Configuring Static Traffic Forwarding with SSM Mapping
Use static traffic forwarding with SSM mapping to statically forward SSM traffic for certain groups.
Beginning in privileged EXEC mode, follow these steps to configure static traffic forwarding with SSM
mapping:
Command
Step 1
configure terminal
Step 2
interface type number
Step 3
ip igmp static-group group-address
source ssm-map
Step 4
show running-config
Step 5
copy running-config startup-config

Monitoring SSM Mapping

Use the privileged EXEC commands in
Table 33-4
Command
show ip igmp ssm-mapping
show ip igmp ssm-mapping
group-address
show ip igmp groups [group-name |
group-address | interface-type
interface-number] [detail]
show host
debug ip igmp group-address

OL-23400-01
Purpose
Enter global configuration mode.
Select an interface on which to statically forward traffic for a multicast
group using SSM mapping, and enter interface configuration mode.
Note Static forwarding of traffic with SSM mapping works with either
DNS-based SSM mapping or statically configured SSM
mapping.
Configure SSM mapping to statically forward a (S, G) channel from the
interface.
Use this command if you want to statically forward SSM traffic for
certain groups. Use DNS-based SSM mapping to determine the source
addresses of the channels.
Verify your entries.
(Optional) Save your entries in the configuration file.
Table 33-4
SSM Mapping Monitoring Commands
Purpose
Display information about SSM mapping.
Display the sources that SSM mapping uses for a particular
group.
Display the multicast groups with receivers that are directly
connected to the router and that were learned through IGMP.
Display the default domain name, the style of name lookup
service, a list of name server hosts, and the cached list of
hostnames and addresses.
Display the IGMP packets received and sent and IGMP
host-related events.
