7.10 Adjusting Control Parameters for Assert

If a multicast device can receive multicast data through the downstream interface, this indicates
that other upstream devices exist in this network segment. The device then sends an Assert
message through the downstream interface to take part in the election of the unique upstream
device.

7.10.1 Establishing the Configuration Task

After basic functions of PIM-SM are configured, you can set the period for holding the Assert
state as required.
Applicable Environment
The configurations in this section ares applicable to the ASM model and the SSM model.
If a PIM-SM switch receives multicast data through a downstream interface, it indicates that
other upstream switchs exist in this network segment. switchs send Assert messages to elect the
unique upstream switch.
The switch can work normally under the control of default values. The S3700 allows users to
adjust the parameters as required.
Issue 01 (2011-10-26)
Run the display pim interface [ interface-type interface-number | up | down ]
[ verbose ] command to check PIM on an interface.
Run the display pim control-message counters [ message-type { assert | hello | join-
prune } | interface interface-type interface-number ]
sent or received PIM control messages.
Run the following commands to check the PIM routing table.
– display pim routing-table [ group-address [ mask { group-mask-length | group-
mask } ] | source-address [ mask { source-mask-length | source-mask } ] | incoming-
interface { interface-type interface-number | register } | outgoing-interface
{ include | exclude | match } { interface-type interface-number | register | none } |
mode { sm | ssm } | flags flag-value | fsm ]
[ number ] ]
– display pim routing-table [ group-address [ mask { group-mask-length | group-
mask } ] | source-address [ mask { source-mask-length | source-mask } ] | incoming-
interface { interface-type interface-number | register } | outgoing-interface
{ include | exclude | match } { interface-type interface-number | register | none } |
mode { sm | ssm } | flags flag-value | fsm ]
[ number ] ]
– display pim routing-table [ group-address [ mask { group-mask-length | group-
mask } ] | source-address [ mask { source-mask-length | source-mask } ] | incoming-
interface { interface-type interface-number | register } ]
NOTE
It is recommended to adopt default values if there is no special requirement.
