IGMP snooping is a L2 feature that allows a L2 switch to listen to IGMP responses from clients and then map the port that the client is reachable on to the multicast mac address of the stream.

The default username and password is cisco/cisco. To see the proxying in action, I’ll enable IGMP debugging on R1 and R2: R1 & R2 #debug ip igmp IGMP debugging is on.
NOTE: If you disable IGMP on a VLAN and then later re-enable IGMP on that VLAN, the switch restores the last-saved IGMP configuration for that VLAN. If there are Cisco or other third party switches in the network, leave this setting disabled. On Cisco switches, IGMP version 2 is enabled by default. igmp-snooping enable quit Configure Switch C: # Enable the IGMP snooping feature. Set the Querier IP to the same address as the switch, or 0.
Enter the following information: In the VLAN ID field, enter 1. From the Privileged EXEC mode of the switch, enter the Global Configuration mode by entering the Step 3. If it is disabled in your switch you can enable it using global command "ip igmp snooping" sh ip igmp int g2/1 shows as IGMP disabled because it is a layer 2 port. We are excited to pursue this goal together with the UNH-IOL,” said Martin Stumpf, Market Segment Manager High Speed Digital Design Test at Rohde & Schwarz.īob Noseworthy, principal engineer, at UNH-IOL, said, “After a successful collaboration with Rohde & Schwarz to develop this MOI, we look forward to further collaboration to extend UNH-IOL high speed cable conformance testing capabilities in the near future.How to enable igmp on cisco switch Switch # configure terminal Switch (config)# ip igmp snooping vlan 105 static 224.

Later this year, we plan to provide automatic scripts based on our R&S ZNrun test sequencer software that will further simplify compliance tests. “The MOIs along with the included state files provide excellent guidance for the industry and describe the test steps as well as the calculations of channel operating margin (COM) and effective return loss (ERL).

The MOI describe exactly how to perform compliance test measurements on high-speed cables and backplanes to fulfil the corresponding specifications. UNH-IOL has created the methods of implementation (MOI) for IEEE 802.3 Ethernet and InfiniBand based on their superior experience. During a period of time in 2020, Rohde & Schwarz, provided UNH-IOL with a state-of-the-art R&S ZNBT40 multiport vector network analyzer with 16 integrated test ports, covering up to 40 GHz, to support efficient testing. UNH-IOL is a worldwide reference for cable compliance tests, and cable manufacturers turn to the interoperability laboratory for their testing services. To secure reliable data transmission with these extremely high data rates, cable compliance tests are highly encouraged to provide confidence in the products. But to bridge short distances, high-speed copper cables are used.
Long-distance transmission in both standards is handled via optical links. InfiniBand, a communications standard to address very low latency and very high throughput rates, opts in the extension planned for 2021 even for throughput rates up to 1,200GB/s when combining several links. The latest specifications planned to be published in fall 2021 for Ethernet IEEE 802.3ck will allow data rates up to 800Gbps. The high data rates need to be transported between computer modules or high-speed data networks. Both have pooled their expertise to provide methods of implementation (MOI) for precise, fast and error-free compliance testing of high-speed cables and backplanes in line with IEEE 802.3 (up to IEEE 802.3ck) and InfiniBand standards (up to rate designator HDR), using vector network analysis test equipment from Rohde & Schwarz.ĭata rates and data traffic grow faster than ever. Rohde & Schwarz and the University of New Hampshire Interoperability Laboratory (UNH-IOL) extend their ongoing collaboration to expand Ethernet and InfiniBand compliance testing. Rohde & Schwarz and UNH-IOL are paving the way for automated compliance tests in line with the latest IEEE 802.3 Ethernet and InfiniBand standards.
