Ping failure with more than 76 bytes on Codian 4510

Hi All,

Through some issue troubleshooting I've stumbled across what seems to be odd behaviour with the Codian 4510. In two seperate environments I've found that pinging the device with a packet size of greater than 76 bytes of data results in timeouts as per below. Does anyone know why this occurs?

localhost:~ jason$ ping -s 76 10.2.0.208

PING 10.2.0.208 (10.2.0.208): 76 data bytes

84 bytes from 10.2.0.208: icmp_seq=0 ttl=254 time=3.642 ms

84 bytes from 10.2.0.208: icmp_seq=1 ttl=254 time=3.579 ms

^C

--- 10.2.0.208 ping statistics ---

2 packets transmitted, 2 packets received, 0.0% packet loss

round-trip min/avg/max/stddev = 3.579/3.611/3.642/0.031 ms

localhost:~ jason$ ping -s 77 10.2.0.208

PING 10.2.0.208 (10.2.0.208): 77 data bytes

Request timeout for icmp_seq 0

Request timeout for icmp_seq 1

^C

--- 10.2.0.208 ping statistics ---

3 packets transmitted, 0 packets received, 100.0% packet loss

This is by design, in order to prevent problems due to excessively large ICMP packets.
