SsmGlobal tab fields
|
DynamicLearning
|
Enables the dynamic learning of SSM channel (S,G) pairs from IGMPv3 reports. As new SSM channels are learned, they appear in the SSM channel table, see "Configuring the SSM channel table."
|
AdminAction
|
Sets the admin state, which determines whether or not the switch uses the table entries.
- none (default) - Does not set the admin state globally so that you can set it for individual SSM channel table entries.
- enableAll - Globally activates all the static entries in the SSM channel table. This setting does not affect the dynamically learned entries.
- disableAll - Globally inactivates all the static entries in the SSM channel table. This setting does not affect the dynamically learned entries.
For information on how this setting affects the switch's behavior, see "Configuring the SSM channel table."
|
RangeGroup
|
Sets the IP multicast group address. The lowest group address is 224.0.1.0 and the highest is 239.255.255.255. The default is 232.0.0.0.
Note: Before changing this setting, see "Changing the SSM range group."
|
RangeMask
|
Sets the address mask of the multicast group. The default is 255.0.0.0.
|
Changing the SSM range group
|
Note:
This procedure re-initializes PIM and temporarily stops all PIM traffic. For those multicast groups out of SSM range (i.e. under PIM-SM behavior), it also causes an RP relearn delay of up to 60 seconds. This delay can be longer if the BSR is local.
|
To change the SSM range group address, you have to perform the following steps:
- Disable PIM.
| If you forget to disable PIM, the following error message opens. |
- Open the SsmChannel tab and delete all of the entries in the SSM channel table.
| If you forget to delete the SSM channels, the following error message opens. |
- Enter the new IP multicast group address in the RangeGroup field.
- Click Apply.
| The following message opens to warn you that every static mroute entry that falls into the new SSM range will be deleted. |
- Click Yes.
- Enable PIM.
