Hi Mr
Thank you for you reply. But still sth i mistake is that This access-list is
applied to in interface.that means when my two servers want to use snmp to mana
ge some devices outside my lan , My server will use the udp port snmp to answer
the sessions, so how the sessions setup with snmp and tacacs ? My snmp server
and Tacacs server is in my Lan port E0
with ip address 202.205.15.x and i want to manage the device connect by my anot
her lan port E1 196.14.0.0.(that is where is my routers and switches, this thin
gs are to be managed).how can i make access-list in my E0 port as out)
Thanks a lot
xihan wang
