CPU: 1.3.6.1.4.1.9.2.1.58

Configure IP on the switch:
<pre>conf t
int vlan 1
ip address 69.55.230.245 255.255.255.0
ip default-gateway 69.55.230.1
en</pre>

Disable telnet:
<pre>conf t
line vty 5 15
transport input none</pre>

DEPRECATED Setup web user, and enable that user to login to web:
<pre>switch-p16(config)#username web privilege 15 password  PASS
switch-p16(config)#line vty 0 4
switch-p16(config-line)#login local
switch-p16(config-line)#en
switch-p16(config-line)#password PASS
switch-p16(config-line)#login
</pre>

Disable web:
<pre>conf t
line vty 0 4
transport input none</pre>

Setup ACL:
<pre>conf t
access-list 1 permit 69.55.230.2
access-list 1 permit 10.1.4.5</pre>

Setup SNMP:
<pre>conf t
no snmp-server community private RW
no snmp-server community public RO
snmp-server community jc292401 RO 1
en</pre>

On mrtg aggregator/host (i.e. mail server) run:
<pre>/usr/local/bin/cfgmaker --if-template=template.pl --show-op-down --global "options[_]: growright,bits" --global 'WorkDir: /usr/local/www/mgmt/mrtg/data' --global 'Interval: 1' --global 'LogFormat: rrdtool' --global 'PathAdd: /usr/local/bin' --global 'LibAdd: /usr/local/lib' --host-template=host.pl jc292401@69.55.230.246 --output=switch-p14.cfg</pre>

And add new switch to crontab script: <tt>/usr/local/www/mgmt/mrtg/mrtg.sh</tt>
