mrtg cfgmaker does read incorrect values over SNMP V1 and V2 and I need to correct the resulting file.
I would like to run a script after creation and use sed if possible. Lines that needs to be corrected in my case are for LAG's and normal ports:
MaxBytes[switch01_lag_26]: 125000000 should go to MaxBytes[switch01_lag_26]: 250000000
(switch01_lag_26 can be switch01_lag_1 until switch01_lag_26)
MaxBytes[switch01_g1]: 12500000 should go to MaxBytes[switch01_g1]: 125000000
(switch01_g1 can be switch01_g1 until switch01_g16)
What sed patterns I have to use to analyze if its a lag or port in the square brackets and then replace the number after the : ?
The html part should show the correct speed if possible too, this is original for port g1:
<h1>Traffic Analysis for g1-- switch01</h1>
<div id="sysdetails">
<table>
<tr>
<td>System:</td>
<td>switch01</td>
</tr>
<tr>
<td>Maintainer:</td>
<td></td>
</tr>
<tr>
<td>Description:</td>
<td>1-Gigabit---Level </td>
</tr>
<tr>
<td>ifType:</td>
<td>ethernetCsmacd (6)</td>
</tr>
<tr>
<td>ifName:</td>
<td>g1</td>
</tr>
<tr>
<td>Max Speed:</td>
<td>12.5 MBytes/s</td>
</tr>
<tr>
<td>Ip:</td>
<td>No Ip (No DNS name)</td>
</tr>
</table>
</div>
and should read at the end (Line below "Max Speed" is changed):
<h1>Traffic Analysis for g1-- switch01</h1>
<div id="sysdetails">
<table>
<tr>
<td>System:</td>
<td>switch01</td>
</tr>
<tr>
<td>Maintainer:</td>
<td></td>
</tr>
<tr>
<td>Description:</td>
<td>1-Gigabit---Level </td>
</tr>
<tr>
<td>ifType:</td>
<td>ethernetCsmacd (6)</td>
</tr>
<tr>
<td>ifName:</td>
<td>g1</td>
</tr>
<tr>
<td>Max Speed:</td>
<td>125.0 MBytes/s</td>
</tr>
<tr>
<td>Ip:</td>
<td>No Ip (No DNS name)</td>
</tr>
</table>
</div>
This is original for LAG 1:
<h1>Traffic Analysis for lag 1 -- switch01</h1>
<div id="sysdetails">
<table>
<tr>
<td>System:</td>
<td>switch01</td>
</tr>
<tr>
<td>Maintainer:</td>
<td></td>
</tr>
<tr>
<td>Description:</td>
<td>lag-1 </td>
</tr>
<tr>
<td>ifType:</td>
<td>IEEE 802.3ad Link Aggregate (161)</td>
</tr>
<tr>
<td>ifName:</td>
<td>lag 1</td>
</tr>
<tr>
<td>Max Speed:</td>
<td>125.0 MBytes/s</td>
</tr>
<tr>
<td>Ip:</td>
<td>No Ip (No DNS name)</td>
</tr>
</table>
</div>
which should read at the end (Line below "Max Speed" is changed):
<h1>Traffic Analysis for lag 1 -- switch01</h1>
<div id="sysdetails">
<table>
<tr>
<td>System:</td>
<td>switch01</td>
</tr>
<tr>
<td>Maintainer:</td>
<td></td>
</tr>
<tr>
<td>Description:</td>
<td>lag-1 </td>
</tr>
<tr>
<td>ifType:</td>
<td>IEEE 802.3ad Link Aggregate (161)</td>
</tr>
<tr>
<td>ifName:</td>
<td>lag 1</td>
</tr>
<tr>
<td>Max Speed:</td>
<td>250.0 MBytes/s</td>
</tr>
<tr>
<td>Ip:</td>
<td>No Ip (No DNS name)</td>
</tr>
</table>
</div>
I can change all speeds in HTML using sed -i 's/\([0-9.]\+\) MBytes/125.0 MBytes/' /switch01.cfg but this changes for LAG's too. How to detect if the HTML part belongs to a LAG?
