Access-list

[SathishkumarSaravanan0348]

Hi All,

In one of the distribution switch I could see the below permit statement are added. Could you please explain the difference between the below  2 lines?

IP access-list extended  XXX  

21 permit icmp X.X.X.X X.X.X.X any

22 permit icmp any X.X.X.X X.X.X.X

Thanks.

21 permit icmp X.X.X.X X.X.X.X any - Is permitting ICMP being sourced FROM x.x.x.x x.x.x.x TO any
22 permit icmp any X.X.X.X X.X.X.X - Is permitting ICMP FROM any TO x.x.x.x x.x.x.x
