P pruning should always be enabled on the ES 2810 when it is connected be tween the device receiving the multicast traffic and an IGMP enabled routing de vice Keep the following in mind when the ES 2810 is located between the multicast transmitter and the IGMP routing device e If the port on the routing device cannot explicitly join the IGMP multicast group IGMP pruning should be disabled on the ES 2810 IGMP pruning can be enabled on the ES 2810 if the router itself can be configured so that the router port connected to the ES 2810 ex plicitly becomes a member of the multicast group via IGMP join messages Page 8 ES 2810 Ethernet Switch Release Notes 3 6 ATM ELANs and Spanning Tree The Spanning Tree Protocol will incorrectly block paths when you have multiple VLANs configured on ports connecting switches connected by Stack Interface Modules and you are using ATM ELANSs This occurs when both e Both switches have a SIM installed no matrix module is used and are connected back to back e The ATM ELAN feature enabled The traffic on the VLAN very likely the system or management VLAN for which the SIM is a member will forwarded but the traffic for the other VLANs will be blocked incorrectly In the VLAN containing the SIM ports if there are multiple paths between the two switches Spanning Tree will correctly block the lower priority path However if there are additional VLANs configured on ports connecting the two sw
