Hi there
I have recently installed 2x N2048P switches in a stack configuration to an existing network. This switch provides PoE service to our IP phones and WiFi access points.
We are having problems being able to pass multicast traffic to/from devices on our wireless network through to Apple TV devices on our core Cisco switch stack.
Some network configuration info -
The Dell stack connects into our core switch stack (Cisco 3750 x5 chassis'). The N2048 has 4 ports configured via LACP (GI1/0/47,GI1/0/48,GI2/0/47.GI2/0/48) for the uplink to the Cisco. These ports each connect into a different Cisco Chassis as such -
Dell GI1/0/47 -> Cisco GI1/0/24
Dell GI1/0/48 -> Cisco GI2/0/24
Dell GI2/0/47 -> Cisco GI3/0/24
Dell GI2/0/48 -> Cisco GI4/0/24
There are a number of VLANs trunked across the port-channel and various individual ports configured on different VLANs.
VLAN 10 = Corporate workstations (SSID: Corp)
VLAN 15 = Access Point management (Cisco APs)
VLAN 25 = Voice
VLAN 30 = Guests (SSID: Guest)
VLAN 50 = Contractors (SSID: Contractor)
All VLANs are configured as Tagged on the LAG.
The ports with WiFi APs are VLAN'd as follows:
VLAN 10 - Tagged
VLAN 15 - Untagged
VLAN 30 - Tagged
VLAN 50 - Tagged
Each SSID associates the client into the correct VLAN and all IP traffic flows as it is meant to.
All our Apple TV devices are on VLAN50 on our Cisco stack. The issue we are facing is that the majority of Apple TV devices are not visible for Airplay from clients on the wireless network. Those that are visible either fail to connect, or will drop out quickly. I believe this is related to Multicast traffic not being forwarded through the Dell switches correctly.
Prior to installation of the Dell switches (only a few days ago!) all our WiFi AP's were on a single 8-port PoE non-managed switch, connected directly into a single port on the Cisco stack. Everything worked well in that configuration.
I have configured IGMP snooping (I think correctly!) but I'm still unable to have the traffic pass properly. I can see MAC addresses listed in the MFDB IGMP snooping table, listed against the port-channel (Po1).
Can anyone assist? Is what I'm trying to achieve possible with the N2000 series?
