CGMP and IGMP Snooping Catalyst Switches Support Matrix

This table provides information related to Cisco Group Management Protocol (CGMP) and Internet Group Management Protocol (IGMP) snooping feature support in Cisco Catalyst Switches.

Catalyst Platform CGMP (Minimum Software Version) Default IGMP Snooping (Minimum Software Version) Default IGMP V3 (Minimum Software Version)
Catalyst 6000 - Catalyst OS (CatOS) Software Not supported(1) N/A Yes (all versions) Enabled (since 5.5.9 and 6.3.1) Yes (7.5) (2)

Catalyst 3550 Not supported(1) N/A Yes (all versions) Enabled Yes (Cisco IOS Software Release 12.1(19)EA1)
Catalyst 3560 Not Supported N/A Yes (Cisco IOS Software Release 12.1(19)EA1) Enabled Yes (Cisco IOS Software Release 12.1(19)EA1)
Catalyst 3750 Not supported(1) N/A Yes (all versions) Enabled Yes (Cisco IOS Software Release 12.1(19)EA1)
Catalyst 2940 Not supported(1) N/A Yes (all versions) Enabled Yes (Cisco IOS Software Release 12.1(19)EA1)
Catalyst 2950/2955 Not supported N/A Yes (all versions) Enabled Yes (Cisco IOS Software Release 12.1(19)EA1)
Catalyst 2960 Not supported N/A Yes (all versions) Enabled Yes (all versions)
Catalyst 2970 Not supported N/A Yes (all versions) Enabled Yes (Cisco IOS Software Release 12.1(19)EA1)
Catalyst 2900XL/3500XL Yes (all versions) Enabled Not supported N/A Not supported
Catalyst 2948G-L3 / 4908G-L3 Yes (supports CMF in all versions)(4) N/A Not supported N/A Not supported

  • (1) The CGMP server feature is supported in Multilayer Switch Feature Card (MSFC), MSFC2, Catalyst 4000 Supervisor Engine III/IV and Catalyst 3550 and 3750 switches. The CGMP Layer 2 feature is not supported.

  • (2) On Catalyst 6500s, before software release 6.3(10), an IGMP Version 3 (V3) packet with more than one group in the same packet was discarded. This is rectified in software release 6.3(10). Software releases 6.3(x) run IGMP Version 2 (V2), and there is no support for V3. An IGMP V3 report is treated as a set of IGMP V2 reports for each of the multicast groups forming the group records in IGMP V3. This happens regardless of the filter mode of the IGMP V3 report. Refer to Cisco bug ID CSCdw61628 (registered customers only) for more information. IGMP V3 is supported beginning with version 7.5 software (only in Supervisor Engine II-based Catalyst 6500 systems), and Cisco IOS Software Release 12.1(11b)E1 or later is required on the MSFC2.

  • (3) For Catalyst 5000s, Supervisor Engine II G or III G, or Supervisor Engine III with a NetFlow Feature Card (NFFC) or NFFC II, is required for IGMP snooping support. Supervisor Engine software release 4.1 or later is required. Certain hardware requires a later version of software. (For example, the NFFC II requires software release 4.3 or later.)

  • (4) Constrained Multicast Flooding (CMF) is a Cisco IOS Software method of performing IGMP snooping. It was created for Cisco IOS Layer 3 switches.

Additional Notes

  1. IGMPv3 join and leave messages are not supported on switches that run IGMP Filtering or Multicast VLAN Registration.

  2. Switches support IGMPv3 snooping based only on the destination multicast MAC address and does not support snooping based on the source MAC address or on the proxy reports.

  • (1) Catalyst 5000 requires Supervisor Engine II, IIG, III, or IIIG for GMRP support.

Additional Notes

  • You cannot enable GMRP if IGMP snooping is enabled.

  • RGMP requires that IGMP snooping is enabled on the switch.

  • Both GMRP and RGMP are disabled by default on all supported switches.
