Changed in Release |
Where Documented |
---|---|---|---|
ip igmp snooping max-gq-miss command |
Configures the maximum number of general query misses permitted for IGMP snooping. |

Configuring IGMP Snooping |
MRIB/M6RIB Dynamic Shared Memory Support |
The Cisco NX-OS IPv4 Multicast Routing Information Base and IPv6 Multicast Routing Information Base (MRIB/M6RIB) dynamic shared memory support feature supports dynamic shared memory in a virtual device context (VDC). Instead of a static allocation of the entire configured memory for the multicast routes, the shared memory for MRIB/M6RIB dynamically adds up or is removed based on the increase or decrease, respectively, in the number of routes. The MRIB/M6RIB dynamic shared memory feature also supports device switchover (from active to standy state and vice-versa) when the shared memory increases or decreases. |
6.2(2) |
MRIB and M6RIB |
Multicast performance enhancement |
Enables enhanced multicast performance on Cisco Nexus 7000 Series Ethernet modules with an XL Option allocated to virtual device contexts (VDCs). |

6.1(1) |
Configuring IGMP |
Configuring F2 modules |
Cisco NX-OS does not support PIM Bidir mode on F2 modules. |
6.0(1) |
Configuring PIM and PIM6 |
Configuring F2 modules |
F2 modules do not support any form of IPv4 or IPv6 tunnels. |
6.0(1) |
Configuring PIM and PIM6 |
Configuring lookup mode to MAC and assigning a static MAC address |
You can configure IGMP snooping to use the forwarding lookup mode as MAC-based, as well as assign a static MAC address. |
5.2(1) |
Configuring IGMP Snooping |
Configuring PIMv4 on GRE tunnel interfaces |
You can configure multicast on GRE tunnel interfaces including outgoing interfaces (OIFs). |
5.2(1) |
Configuring PIM and PIM6 |
Configuring multicast interoperation with F Series modules |
You can configure multicast interoperation with F series and M series modules. |
5.1(1) |
Configuring Multicast Interoperation with N7K-F132-15 Modules |
Multicast routing initial holddown period |
You can specify the initial holddown period for both IPv4 and IPv6 networks. |
4.2(1) |
Configuring PIM and PIM6 |
Use a route-map policy for commands |
You can specify group prefixes in a route-map policy rather than specifying them on the command line for these commands:
|
4.2(1) |
|
Virtual Port Channel (vPC) |
Cisco NX-OS software for the Nexus 7000 Series devices does not support PIM SSM or Bidr on vPCs. Cisco NX-OS software fully supports PIM ASM on vPCs. |
4.1(4) |
Virtual Port Channels and Multicast |
Virtual Port Channel (vPC) |
A virtual port channel (vPC) allows a single device to use a port channel across two upstream switches. |
4.1(3) |
Virtual Port Channels and Multicast Verifying the IGMP Configuration |
Immediate leave |
Option that minimizes the leave latency of IGMPv2 or MLDv1 group memberships on a given IGMP or MLD interface because the device does not send group-specific queries. |
