Q:MSR3600-51 ping 直连PC的时候有报错
<H3C>ping 1.1.1.1
Ping 1.1.1.1 (1.1.1.1): 56 data bytes, press CTRL_C to break
88 bytes from 1.1.1.1: icmp_seq=0 ttl=128 time=0.988 ms
wrong total length 116 instead of 84
*May 19 14:24:54:056 2017 H3C SOCKET/7/ICMP:
ICMP Output:
ICMP Packet: src = 1.1.1.2, dst = 1.1.1.1
type = 8, code = 0 (echo)
*May 19 14:24:54:056 2017 H3C SOCKET/7/ICMP:
ICMP Input:
ICMP Packet: src = 1.1.1.1, dst = 1.1.1.2
type = 0, code = 0 (echo-reply)
A:
正常情况:发送报文为ICMP报文载荷56字节,加上8字节ICMP报头,加上20字节IP报头, IP层之上一共84字节。接收报文封装相同;
<H3C>ping 12.1.1.1
Ping 12.1.1.1 (12.1.1.1): 56 data bytes, press CTRL_C to break
56 bytes from 12.1.1.1: icmp_seq=0 ttl=255 time=0.000 ms
报错情况:发送报文为ICMP报文载荷56字节,加上8字节ICMP报头,加上20字节IP报头, IP层之上一共84字节。接收报文ICMP载荷88字节,加上8字节ICMP报头,加上20字节IP报头,IP层之上一共116字节,所以产生了wrong total length 116 instead of 84的报错。
