I have multiple servers attached to this switch-A.but not discover by UT not all but some of them. when I run sh mac-address-table on the switch I have found the missing server mac-address, also when I have run sh ip-arp to the mls switch which is the switch-A attached too. I have seen the correct mac-to-ip address translation for all servers not discovered by UT.
I don't know related to this but when I run snmpwalk from device center from this switch-A for "ifDesc. and did not show all the interface.this switch has 9 blades but ifDesc show only for the first 3 blades?not sure UT and snmp related too. just to give background. or any switch configuration issue.
