a) a unix base machines, which connect to
b) some layer 2 switches, and these are distributing by
c) a couple of layer 3 switches, i mean, Cisco Catalyst switches which operating inter-vlan routing, and
d) few routers, which running very good and stable dynamic IGP routing, plus
e) core level routers, which aggregate routes and establish via bgp to another network.
After verify that this network is working fine, i need to
i) install unix base application which use SNMP protocols to gather network information and utilization and put in a file in unix.
ii) create a CRON job which trigger the PERL scripts to grep require information, to operate and compare for monitoring which should trigger another unix base application to send alerts (sms, emails) to me on certain condition.
iii) after that, i'll put some firewalls on the edge fields.
------------------------------------------------------------
Alright, for those things, i need to understand following.
i) advance routing and switching ( layer 2 and 3)
ii) comfortably using unix or linux platform (cron jobs manageable)
iii) Perl Scripting
---------------------------------------------------------------------
Now i'm searching for some Perl books to references, routing is no problem, just finished my Route exam, for switching, currently reading the Cisco Press books. for linux, using latest Ubuntu. Goodluck myself !!!
