System view 

sys-contact: Contact information for system maintenance, a string of up to 200 characters. 

sys-location: Geographical location of the device, a string of up to 200 characters. 

version: Specifies the SNMP version to be employed. 

v1: Specifies SNMPv1. 

v2c: Specifies SNMPv2c. 

v3: Specifies SNMPv3. 

all: Specifies all the SNMP versions available, that is, SNMPv1, SNMPv2c, and SNMPv3. 

Use the snmp-agent sys-info command to set the system information, including geographical location 

of the switch, contact information for system maintenance, and the SNMP version employed by the 

switch. 

Use the undo snmp-agent sys-info location command to restore the default contact information and 

geographical location, or stop the running of the corresponding SNMP version. 

If the switch fails, you can contact the switch manufacturer according to the system information. 

The SNMP versions of the device and the NMS must be consistent; otherwise data exchange cannot be 

completed. 

The device processes the SNMP messages of the corresponding SNMP version when the SNMP 

version is enabled on the device. If only SNMPv1 is enabled, while the device receives SNMPv2c 

messages, the messages will be discarded; if only SNMPv2c is enabled, the device discards the 

received SNMPv1 messages. 

Multiple SNMP versions can be running the on the device at the same time to allow access of different 

NMSs. 

By default, the contact information of a Switch 5500-EI is " 3Com Corporation.", the geographical 

location is " Marlborough, MA 01752 USA", and the SNMP version employed is SNMPv3. 

You can use the display snmp-agent sys-info command to display the current SNMP system 

information.
