[Asterisk-Users] Cisco 7960 dual ethernet port - bandwidth impact

[Rich Adamson]

FYI for anyone using the dual ethernet ports on a Cisco 7960.

I'm using a Cisco 7960 connected to an HP2524 10/100 switch, which has 
an asterisk box connected directly to it. No VLANs defined or in use.

Measured bandwidth:
  PC -> HP Switch -> Asterisk : actual throughput measured at 94.1 mbps.

  PC -> 7960 -> HP Switch -> Asterisk : actual measured at 93.02 mbps.

The second test (through the 7960) was conducted with a g711 
conversation in progress with absolutely no noticeable impact to the 
audio quality. The 7960 was running sip v7.1 firmware.

The bandwidth tester (older version of NetIQ's QCheck) sent one megabyte 
  bursts of tcp traffic between the two endpoints using 1514 bytes packets.
