Cisco SLM 2008 is a very efficient layer 2 manageable gigabit ethernet switch, with decent pricing and a large range of features: VLAN, (R)STP, LACP and static link aggregation, 802.1X Authentication, IGMP Snooping, you name it. Even the integrated web interface is quite well designed and not buggy.<\/p>\n
But one (native) feature is lacking when you want to monitor per-port network traffic : SNMP.<\/p>\n
Here is how to enable and basically configure SNMP on SLM2008 switches.<\/p>\n
First, download this script: ename_snmp.pl<\/a> (Note for Chrome\/Safari users: this file may be downloaded as enable_snmp.download, I don’t know why.)<\/p>\n Then there are two ways of using this script :<\/p>\n * remotely by directly altering the switch configuration file.<\/p>\n * locally by first download the switch configuration file, alter it and upload it to the switch.<\/p>\n There is the detail about the remote way, since I used it:<\/p>\n * Configure everything you need in the SLM2008 web interface, especially on the \u00ab\u00a0System\u00a0\u00bb page.<\/p>\n * Open a terminal in the directory where the script was downloaded.<\/p>\n * chmod +x enable_snmp.pl<\/tt> for making the script executable.<\/p>\n Then:<\/p>\n You will have to provide the right information for <\/tt>, <\/tt>, <\/tt> and <\/tt> parameters.<\/p>\n Finally, use the following command from an host that has network access to the switch:<\/p>\n A long output should be displayed, showing every piece of information the embedded SNMP daemon on the SLM2008 can serve.<\/p>\n I hope this will help.<\/p>\n Regards.<\/p>\n Credits: Cisco support forum<\/a> and David Holland.<\/p>\n","protected":false},"excerpt":{"rendered":" Cisco SLM 2008 is a very efficient layer 2 manageable gigabit ethernet switch, with decent pricing and a large range of features: VLAN, (R)STP, LACP and static link aggregation, 802.1X Authentication, IGMP Snooping, you name it.
