I know, I know.. I haven't blogged in ages!
I have actually passed my BCMSN since the last time I blogged, so now working getting the BSCI out of the way before the end of May. Then i'll have a few weeks before and after my holiday to do ONT and complete my CCNP under the current track!
As part of my BSCI studies, i've just come across this command
R1#sh ip port-map
Default mapping: snmp udp port 161 system defined
Default mapping: echo tcp port 7 system defined
Default mapping: echo udp port 7 system defined
Default mapping: telnet tcp port 23 system defined
This will be very useful when creating ACLs etc!
