Hi, there, I am looking for a tool that can trace a path on HTTP or HTTPS level, simular to traceroute but on different tcp/udp ports. It looks like it is not easy to find. Any suggestion? Thanks, Han   ... View more

We have Bluecoat proxies with Inline mode. I find from our inside network, the trace to google goes through a different path than to the proxies. The IE has configured with the URL of the proxies for HTTP traffic   User---GW---R1-R2--Internet---Google User--GW---R1--R9--proxies   I wonder how does a router in between know whether this is a HTTP traffic or not?   Thanks, Han ...

A typical topology, 2 7Ks at core, two 5Ks crossed connected to the 7ks. then, there are two extenders. I want to created two VDCs on the 7Ks, let called it VDC A, representing zone Aand VDC B() representing zone B. How can i extend the VDCs to 5Ks? For instance, can i have both zones A and B on both 5ks? if yes, how do you do that? On each of the 5Ks, create two VDCs, and using physical connections to ports on 7Ks that allocated to the VDCs seperatedly? All I want is when connecting a devices to a port(say port 10) on 5K, it goes to VDC A on 7Ks, another port(say port 20) on 5K, it connects to VDC B on the 7Ks. thanks, Han ... View more
