Is there a switching product that can be configured to classify untagged ethernet (ip) frames arriving at a switch port into two categories: VoIP bearer streams and non-VoIP bearer streams, such that the VoIP stream gets mapped to a specific VLAN (with specific 802.p value) and the non-VoIP streams remain untagged, and both streams are forwarded to a single egress port.
To clarify, can the switch identify the VoIP flow by inspecting the IP header in an untagged Ethernet, IP encapsulated frame on on receipt at the ingress port, and then insert a VLAN tag when transmited on egress port. Obviously this assumes some layer 3 capability in the switch.
[toc:faq]The ProblemOn traditional switches whenever we have a trunk
interface we use the VLAN tag to demultiplex the VLANs. The switch needs
to determine which MAC Address table to look in for a forwarding
decision. To do this we require the switch to do...
[toc:faq]Introduction:Netdr is a tool available on a RSP720, Sup720 or
Sup32 that allows one to capture packets on the RP or SP inband. The
netdr command can be used to capture both Tx and Rx packets in the
