Nightly cross-site backups swamp the link, and this has caused problems [...]

How can we do MAC address binding in Layer 2 (L2) and Layer 3 (L3) switches?
Is it necessary to apply no IP route cache on virtual local area networks (VLAN) interfaces in an L3 switch and why? What are the advantages or disadvantages?
If a Layer 3 switch is faster than a router, why can’t we use an L3 in place of a router?
like layer 2 protocol in cisco called VTP , while in hp procurve is called GARP , I need to know the other similarities in both for layer 2,3
Why do we use Layer 3 (L3) switches, and how are they different from Layer 2 (L2) switches?
Hi Friends, I have a small requirement. please see my configuration. i have an L3 switch (Cisco 3560) series and now i am forwarding all the traffic from my network to Firewall from L3 switch through this default route ” ip route 0.0.0.0 0.0.0.0 10.11.12.2″ where 10.11.12.1 is my L3 switch 10.11.12.2 is my firewall [...]
