Hi guys and guyettes, Trying to turn to crowd knowledge here. Without IGMP Querying/Snooping, Multicast traffic is treated in the same manner as a Broadcast transmission, which forwards packets to all ports on the network. This latest generation of access switches supports cost-effective cloud-scale deployments, more endpoints, and is capable of wire-rate security and telemetry. Network switches with IGMP snooping listen in on the IGMP conversation between hosts and routers and maintain a map of which links need which IP multicast transmission. # ensure igmp snooping params supported in this module are in there default state-cisco. 0/24 in the filters (uPNP, mDNS and so on), so you might want to exclude (permit) these in your filters: Switch#show ip igmp snooping groups Vlan Group Type Version Port List-----12 224. 12.

Internet Group Management Protocol (IGMP) is the protocol used by IPv4 end hosts to indicate their interest in receiving multicast traffic for certain multicast groups to neighboring multicast routers. The Cisco Catalyst 9300 Series is made up of seven different switch models. (IGMP) snooping groups 32,000 (without vPC) 32,000 (with vPC) Maximum number of Cisco Nexus 2000 Series Fabric Extenders per switch 16 Number of access control list (ACL) entries 4000 ingress 1000 egress Maximum number of VLANs 4096 Maximum number of Virtual Routing and Forwarding (VRF) instances 1000 Synchronization of HSRP and IGMP snooping Cisco Fabric Services is enabled by default when vPC feature is turned on. end . In multicast scenarios, IGMP snooping is needed to switch traffic, and a large multicast route (mroute) capacity may be needed to route traffic. For those cases, please remind to activate at least one IGMP querier somewhere on I recently happened upon a familiar problem with IGMP Snooping on a Layer 2 topology comprised of Cisco Catalyst 6504 and 4948 switches. As the name implies, this is done by listening to IGMP traffic between the router and hosts: When the host sends a membership report for a multicast group then the switch adds an entry in the CAM table for the interface that is connected to the host. Maximum: 32,000 Synchronization of HSRP and IGMP snooping Cisco Fabric Services is enabled by default when vPC feature is turned on. IGMP Explicit Tracking IGMP Snooping issue. IP-based look-. You can always check if there is an active querier after enabling snooping with the command: show ip igmp interface vlan XXX | include querying (in 12. (IGMP), PIM Stub, Weighted Random Early Detection (WRED), First. g. IP Multicast Routing Configuration Guide, Cisco IOS XE Bengaluru 17. When Cisco’s IGMP Snooping stops working for a few seconds. IGMP snooping allows us to constrain our multicast traffic. PDF - Complete Book (6.

The Catalyst 9300 Series is designed for Cisco StackWise Layer 2 switch provides a complete lineup of features including IGMP snooping, port mirroring, and Cisco SG300 switch identifies itself as duplicate IP address. Cisco NX-OS does not support PIM Bidir mode on F2 modules. In layer-3 tests, the Catalyst 4948E forwarded traffic to 28,000 multicast routes (mroutes). Cisco Nexus 9300 Series Switches 1000 ¦ IGMP snooping entries: 32000 ¦ ACL entries Symptom: IGMP snooping querier configured on two Nexus5k switches in VPC. Cisco Nexus 9000 Series switches support IGMP snooping with vPCs. ROUTER SWITCH LIMITED 3 NEXUS 9300 SWITCHES CHARACTERISTICS Table 1.

(CVE-2018-0292) This is the relevant config on the cisco switch:! ip igmp snooping vlan 115 querier version 2. Cisco IOS routers support a number of banners, here they are: MOTD banner: the “message of the day” banner is presented to everyone that connects to the router.

VLAN IDs 1002―1005 are reserved for Token Ring and FDDI VLANs, and cannot be used in IGMP snooping. If you want the devices to accept the IGMP general query messages, configure the IGMP snooping querier to run IGMPv1. Internet Group Management Protocol (IGMP) snooping constrains the flooding of IPv4 multicast traffic on VLANs on a device.
