Full Discussion: Want to terminate command execution when string found in the command output
Top Forums Shell Programming and Scripting Want to terminate command execution when string found in the command output Post 302713033 by elixir_sinari on Wednesday 10th of October 2012 07:31:30 AM

Code:
Did not find 'MplsVpnName' in module MPLS-VPN-MIB (/usr/local/share/snmp/mibs/mib-jnx-ldp.txt)
IF-MIB::ifDescr.2500 = STRING: ae0.784
Timeout: No Response from 182.19.96.13

Not all those lines which you get in the output are seen by the grep command. The 1st and 3rd lines have been written by your command snmpwalk to standard error (by default the terminal). The 2nd line has been filtered by the grep command.

Is this what you need?
Code:
snmpwalk -v 3  -u WANDL_SU -a MD5 -A vfipmpls -x DES -X VfIpMpLs -l authPriv 182.19.96.13 2>/dev/null|awk '/ae0\.784/{print $NF}'

snmp_hostres

SNMP_HOSTRES(3) 					   BSD Library Functions Manual 					   SNMP_HOSTRES(3)

NAME

     snmp_hostres -- host resources module for bsnmpd(8)

LIBRARY

     (begemotSnmpdModulePath."hostres" = /usr/lib/snmp_hostres.so)

DESCRIPTION

     The snmp_hostres module implements the HOST-RESOURCES-MIB as standardized in RFC 2790.

RESTRICTIONS

     Not all information in the MIB is meaningful in FreeBSD or is available.  The following variables are not implemented or carry no informa-
     tion:

     hrFSType
	     There are several types of file systems for which no appropriate OID exists yet which are supported by FreeBSD.  For smbfs, procfs
	     and devfs , hrFSOther is returned.  In all other cases, hrFSUnknown.

     hrFSBootable
	     It is questionable what bootable means here.  Does it mean that the BIOS is available to start a boot on that file system or does it
	     mean that there is something bootable?  In either case this information is not available so this variable returns True for the root
	     file system (which is not necessarily correct) and False for all others.

     hrFSLastFullBackupDate, hrFSLastPartialBackupDate
	     This is not available and always returns an empty string.	Theoretically, this could be retrieved from /etc/dumpdates, which would
	     hardly be correct given the different ways of doing backups.

     hrDiskStorageTable
	     Floppy devices are currently not reported.  Also the names of the disks are hard-coded in the module.

FILES

     /usr/share/snmp/mibs/HOST-RESOURCES-MIB.txt

     /usr/share/snmp/mibs/BEGEMOT-HOSTRES-MIB.txt
	     This is the MIB that is implemented by this module.
