Switchport Block Multicast 2960. I apparently mistakenly assumed that once applied to an interf

I apparently mistakenly assumed that once applied to an interface that it would block all of the multicast traffic on that interface regardless of VLAN. This document explains the required steps to configure Cisco 2960 switch specifically. Also, the storm-control feature could be used to limit the amount of I am trying to take a switch port from voice vlan and put into only access vlan. 2 (2)E (Catalyst 2960, 2960-S, 2960-SF and 2960-Plus Switches) When the storm control threshold for multicast traffic is reached, all multicast traffic except control traffic, such as bridge protocol data unit (BDPU) and Cisco Discovery Protocol Note When the storm control threshold for multicast traffic is reached, all multicast traffic except control traffic, such as bridge protocol data unit (BDPU) and Cisco Discovery When the storm control threshold for multicast traffic is reached, all multicast traffic except control traffic, such as bridge protocol data unit (BDPU) and Cisco Discovery Protocol (CDP) frames, イーサネットインターフェイスのデフォルト設定普段あまり意識することはありませんが、 Catalystのレイヤ2イーサネットインターフェイスのデフォルト設定は以下のよう There is no support for them on 2950/2960/3550 switches. Вставить ник This article applies to all Easy Managed Smart Switches with an Easy Smart user interface (UI), including the Nighthawk S8000 model Software Configuration Guide, Cisco IOS Release 15. 00 ! With multicast traffic, the port blocking feature blocks only pure Layer 2 packets. И еще она не действует на IPv4 и IPv6 пакеты. interface GigabitEthernet1/0/1 switchport block multicast storm-control multicast level 0. Switchport blocking does not offer levels of control. When the storm control threshold for multicast traffic is reached, all multicast traffic except control traffic, such as bridge protocol data unit (BDPU) and Cisco Discovery Protocol What is the best way to do that command wise? I have seen multiple suggestions. 0G, 2960S, and 2960X Configuration for WheatNet-IP Overview Let’s take a look at what needs to be done to get your Cisco 2960 ready for the To add a multicast router port (add a static connection to a multicast router), use the ipv6 mld snooping vlan mrouter global configuration command on the switch. The best one I can come up with is: (config-if)# switchport block multicast However I am still seeing multicast When the storm control threshold for multicast traffic is reached, all multicast traffic except control traffic, such as bridge protocol data unit (BDPU) and Cisco Discovery Protocol Документация утверждает, что 'switchport block multicast' блокирует отправку трафика в порт, а не прием. This example shows how to block unicast and multicast flooding on a port: Switch# configure terminal Switch (config)# interface gigabitethernet0/1 Switch (config-if)# switchport block multicast At times in a switching environment, unknown unicast or multicast traffic on LAN is flooded to switch ports because of one of 2 You could use the block multicast command on the switchport to cover that, and then use igmp snooping to have the switch know what hosts actually want multicast traffic. SWtich type: switch 1 provision ws-c2960s-48lpd-l Quick couple of lines to disable multicast traffic on a specific interface or port. I do not want any multicast traffic flowing Chapter 2 Catalyst 2960 Switch Cisco IOS Commands switchport block switchport block Use the switchport block interface configuration Note When the storm control threshold for multicast traffic is reached, all multicast traffic except control traffic, such as bridge protocol data unit (BDPU) and Cisco Discovery I tried configure 2960: no switchport block unicast no switchport block multicast switchport mode access disable storm control disable igmp add static records in MAC address At times in a switching environment, unknown unicast or multicast traffic on LAN is flooded to switch ports because of one of 2 When you block unknown multicast or unicast traffic for a port channel, it is blocked on all ports in the port-channel group. These commands may be applicable to other members of the Port Blocking can be used to disable flooding of multicast, broadcast or unknown unicast from one port to others. Multicast packets that contain IPv4 or IPv6 information in the .
