Does the GS305/P pass VLAN tags and LLDP?

Does the GS305 and 305P switch line preserve incoming VLAN tags when it forwards to outgoing? Also will it pass LLDP? We had a colleague accidentally submit a PR for some GS305P to be placed between several computers/VoIP phones and a larger Cisco switch. The phones receive the voice VLAN ID through LLDP coming from the Cisco. I know we can always test it but if there's confirmation the Netgear can't do it I can cancel the PR before shipping. Thanks

    Many unmanaged Ethernet switches do.

    Similar to the above - some unmanaged Ethernet switches do.

     

    Personally, I would not expect LLDP will forwarded out of scope:  For the obvious reason - LLDP it defined as Link Layer. Interestingly we sometimes see LLDP packets (multicast destination addresses from the 01:80:C2 block) leaking...

     

    Both "effects" are certainly in in no form (neither positive nor negative) features on an unmanaged class switch. Said this: Certainly the wrong switch for this location on the network!

     

    Neither blocking nor forwarding 802.1q frames (e.g. with VLAN tags) are features defined the data sheet.
    The same applies to any kind of Spanning Tree 802.1d, and the related 802.1w frame (addresses).

     

    So no reason for a PR, not a faulty product, nor a reason to return the switches IMHO. These switches are working as they have to...

    PS. Mind you, talking to the community here - and in no aspect a formal support channel.

  • Thanks for the reply. Just for clarification, I intended "PR" to mean "purchase request", meaning we have submitted for approval but haven't actually ordered. We've canceled the request and are going with an equivalent Cisco 8-port switch which definitely supports both VLANs and LLDP. Thanks again.
