35PIM-Source Specific Mode (PIM-SSM)The protocol-independent multicast (PIM)-source specific mode (PIM-SSM) commands are supported by the DellForce10 operating software (FTOS) on all E-Series, C-Series, S-Series, Z-Series, or S4810 platforms.ip pim ssm-rangeSpecify the SSM group range using an access list.C-Series, E-Series, S-Series, Z-Series, S4810Syntax ip pim ssm-range {access_list_name}Parametersaccess_list_nameEnter the name of the access list.Defaults Default SSM range is 232/8 and ff3x/32Command Modes CONFIGURATIONCommand History Version 8.3.11.1 Introduced on the Z9000.Version 8.3.7.0 Introduced on the S4810.Version 8.1.1.0 Introduced on the E-Series ExaScale.Version 7.8.1.0 Introduced on the S-Series.Version 7.7.1.0 Introduced on the C-Series.Version 7.5.1.0 Introduced on the E-Series.UsageInformationFTOS supports standard access lists for the SSM range. You cannot use extended ACLs forconfiguring the SSM range. If you configure an extended ACL and then used in the ip pimssm-range {access list name} configuration, an error is reported.However, if you configure ip pim ssm-range {access list name} first and thenyou configure the ACL as an Extended ACL, an error is not reported and the ACL is not appliedto the SSM range.FTOS-recommended best-practices are to configure the standard ACL, and then apply the ACLto the SSM range. After the SSM range is applied, the changes are applied internally withoutrequiring clearing of the tree information base (TIB).When the ACL rules change, the ACL and protocol-independent multicast (PIM) modules applythe new rules automatically.1147
