Hi,I have a question about "priority percent" command.I want to deploy QoS at customer network to make sure voice traffic with DSCP46 and be treated with highest priority. All the packets makred with DSCP 46 will be put into LLQ on Cisco 3845 router,...
My question is if Cisco Catalyst switch can rewrite the CoS correctly between ISL and 802.1Q encapsulated packets.For example, packet with CoS 5 was encapsulated with 802.1Q and received by switch, if switch can write the same CoS value on the packet...
Voice packet was marked with DSCP EF, switch port was set to "trust dscp".As I known, most of Cisco switch and modules support only CoS maps to egress certain queue before sending out. My question is:if I only trust dscp at ingress port, the dscp val...
Hi,I want to config end-to-end QoS on my network. The only question left is that:At the core layer, 2 Cat6500 connect to each other by layer 3 Gi interface with IP address, I don't know what's the difference between L2 and L3 interface QoS confiurati...
I have a question about RTP when optimize our VoIP network.That is how Cisco router verify a packet as a RTP packet?When capture a voice packet,how the router analyze the packet,and how router know it's a RTP packet? Thanks!
Dear Nirajan,Thanks for your quick reply!Actually, the Smartbit sent two seperated flows, each flow is 20Mbps which can make the 10Mbps WAN link congested.I can see how many packets got passed and how many packets sent from port per-second on the out...
thanks for your reply.This problem has been resolved.It's a compatibility issue between Cisco7609 and E1/Ethernet convertor.Other port on 7609 can auto-negotiate with the same vandor convertor successful to 100M-Full,but only this port can't,I had to...
Thanks for your reply!1,I has changed the port speed and duplex,but it's same,70% packets lost.2,show interface fa 8/29,no error.Would you tell me why if I connect notebook which instead of 7609 to network,no cable changed,no packets lost.
Thanks for your reply.I has done some test.1,Replace 7609 with a notebook configed the same address as 7609,NB can ping CE successfully without packet lost.The topo is:NB---E1 convertor---ISP E1 line-----E1 convertor---CE router.2,Plug the UTP cable ...
