I hope you have found the solution. If you happen to come across this please post your solution.
Following might help others in future.
I have done similar using snmp check through Nagios
or you can do the shell check using the following but make sure that you have configured your cisco device(monitored device) with at least the following

snmp-server community password RO accesslist number

password= is the community-string
RO = read only
access list number which allows the source ip to query the cisco device.
Note: I have noticed the behaviour on some Cisco switches that if the access list is not configured then it will allow access from anywhere even access list number is written the snmp command (Should give you error because of security)

form the Linux shell (monitoring box)
snmpwalk walk through all the OID values under a MIB tree , where as snmpget only gets the results for exact OID value. BTW
snmpwalk -v2c ipaddress community-string-password .1.3.6.1.2.1.2.2.1.7
above will check all under .1.3.6.1.2.1.2.2.1.7.?
snmpget -v2c 192.168.0.1 comunity .1.3.6.1.2.1.2.2.1.7.27
above will check only Serial2/0:0

Replace the OID value to the OID value of E1 interface value (You can get that from Cisco website)
