SNMP¹ is an SNMPv2c monitoring application for Cisco Routers and Switches. It gives you near realtime updates for system CPU, memory and interface utilization. This app is important if you need to know what your Cisco Router or Switch is doing. Enterprise monitoring apps can only offer you 2 to 5 minute intervals for statistic updates. While these apps do offer historical and trend analysis, SNMP¹ will augment your monitoring portfolio by monitoring a critical device near realtime. SNMP¹, or SNMP to the power of one, will let you monitor one Cisco router or switch at a time. This will focus a network administrators attention to that target system.
**Please be aware of your network policies prior to purchase**
Requirements:
-SNMP UDP/161 access to the target Cisco router or switch
-SNMP ReadOnly access
Security considerations:
-SNMP ReadOnly access on the target Cisco router or switch
Example Basic Cisco IOS config:
access-list 50 permit 10.1.20.0 0.0.0.255
!
snmp-server community [communityString] RO 50
snmp-server ifindex persist
...or the following example would restrict ReadOnly access to required MIBs:
access-list 50 permit 10.1.20.0 0.0.0.255
