Query switch for mac table snmp5/12/2023 When doing this same query against an HP ProCurve 1810G switch (24 ports), the. To use the SNMP version 1 or 2c platform in your installation, add the following to your configuration. Port 31 matches the values I get using the cisco IOS show mac address-table. It is recommended to use Ping or Nmap instead. However, since devices are not removed until they time out, this is less effective for device tracker integration page than desirable. This reflects all recent devices seen on the network. The following OID examples pull the current MAC Address table from a router. It could be that you need to install the SNMP support manually. Internet 172.16.1.5 1 device tracker needs SNMP to be enabled on the router. Protocol Address Age (min) Hardware Addr Type Interface MAC authentication controls network access by authenticating source MAC addresses on a port whereas Port security features combines and extends 802.1X and MAC authentication to provide MAC-based network access control. Re: Query Id: 22022 Hewlett Packard Enterprise (HPE) welcomes your feedback. Total Mac Addresses for this criterion: 6 Re: HP5130 switch SNMP and local MAC AUTHENTICATION. S01#sh ver | i IOSĬisco IOS Software, C3560 Software (C3560-IPBASEK9-M), Version 12.2(37)SE, RELEASE SOFTWARE (fc2) I am including some show commands from the switch, in case you have questions about the CLI for the SNMP commands above. Loading MIBs allows you to poll with an OID name, instead of the long dotted number. If you haven't loaded all Cisco's MIBs on your Ubuntu machine, then you should avoid using the -m flags in the snmpbulkwalk commands. ![]() I don't remember Ubuntu cleaning out /tmp, but to be safe I'd avoid storing things there. You should use your HOME directory in linux to store the file. rootAHV dmesg grep -i . CentOS) clean out the /tmp directory on a monthly basis. Querying the switch from AHV using lldpctl shows PortID as local .1.3.6.1.2.1.3.1.1.2 > ~]$ cat /tmp/S01_ARP.txtĪs you see above, you can use cat in linux to get all output from a text file. We're delving into areas that go outside the normal scope of this site, but to save the ARP table above to a file in /tmp/S01_ARP.txt, the you'd add > /tmp/S01_ARP.txt to the end of the snmpbulkwalk above. If you really want the ARP table from the switch, then you need to poll atPhysAddress. Keep in mind that Vlans 1002-1005 are internal Cisco Vlans that you should not poll. If you're not sure which vlans to poll on a switch, you can get that information from. Thus we know that all the mac-addresses on this switch were learned through FastEthernet 0/48 in vlan-10. BRIDGE-MIB does that with dot1dBasePortIfIndex. To translate that into a normal interface name, you have to map that to an ifName. In the output above, 52 is the value of dot1dBasePort, which is a number the MIB uses to index the dot1dTp table. In my example below, the switch at 172.16.1.210 is configured with snmp-server community public ro, and I'm polling the mac-address table in vlan-10 with dot1dTpFdbPort from BRIDGE-MIB. When the SNMP agent is first initialized, the SNMP engine ID is set to the base MAC address of the switch appended to the enterprise value for OmniSwitch. each vlan you poll needs a different community. If you really want the mac-address table from the switch, then remember you have to change the community string you poll with. I wish polling with SNMP wasn't as complicated. I apologize in advance for the length of this answer. you just need to remove the -m option in the commands if you don't have the MIBs loaded locally. Some of my examples assume you have the MIBs loaded on your server. ![]() please let me know if you need pointers for doing this (see this question for hints about loading MIBs in linux). I am assuming you know how to login to your Ubuntu server, and that NET-SNMP is installed. ![]() 1.3.6.1.2.1.17.4.3.1.2 however, that OID actually is for the mac-address table in the switch. you are asking about ARP tables, and you're using OID.
