Network Topology; Known Limitations - SpectraLink NetLink e340 Supplementary Manual

Network Topology

The following topology was tested during VIEW Certification. It is important to note
that these do not necessarily represent all "Certified" configurations.
Both Layer 2 and Layer 3 roaming were tested. Layer 3 roaming of NetLink Wireless
Telephones requires the use of a tunnel.

Known Limitations

During VIEW Certification testing, the following limitations were discovered.
1. You cannot have WPA-PSK and WPA2-PSK configured on handsets simultaneously
within the same ESSID. The phones will not check in.
2. You must disable IGMP snooping when running SpectraLink's SRP protocol (used
with NetLink Telephony Gateways). SRP uses multicast packets to check-in which
are not forwarded through the Wireless Switch when IGMP snooping is enabled.
When a tunneled VLAN is configured over a Layer 3 network, IGMP snooping
must be disabled each time the tunnel is established, because the virtual VLAN is
established with IGMP snooping turned on by default.
3. RF Active Scan must be disabled on AP3750 radios that are providing voice services,
including NetLink Wireless Telephones.
