Hi All,
I am implementing a new switch and using ASR1001-X as my core routers on which I am experiencing a strange issue. Firstly on one of the ports in ASR router (gi0/0/2) I was getting huge drops when I was pinging directly connected devices, then when I moved the connection to other interface (gi0/0/3) I was able to ping the directly connected device but with a difference.
On gi0/0/3 interface I was getting 100 % result when I pinged with even packet size but got huge drops when I pinged with odd packet size.
router-1#ping 1.1.1.2 size 1472 repeat 100
Type escape sequence to abort.
Sending 100, 1472-byte ICMP Echos to 1.1.1.2, timeout is 2 seconds:

Success rate is 100 percent (100/100), round-trip min/avg/max = 1/10/16 ms

Type escape sequence to abort.
