UT for hosts in DMZ

ohassairi
Level 5
Level 5

hello

CWLMS 3.2 can see most of computers in UT end host.

However we have some servers that it cannot see. These one are located in ASA firewall DMZs.

Is this normal ? or is there any way to  let it see these servers?.

Notes:

1-      CW can ping these servers

2-      These servers are connected to discovered Cisco switches

Your SNMPv3 configuration looks wrong.  You've assigned the VLAN contexts to a group, campusgroup; however, I think you wanted to assign them to MLMg.  That is, you need to use the group of which your SNMPv3 user is a member.

These end hosts should be visible in UT provided the switches are data collected by Campus, and show up as green on the Campus topology map.  In other words, there should be nothing different between UT getting end hosts from these switches vs. any others on the network.  The only problem you may see is that UT will not get their IP addresses as it sounds like the ASA is routing for these DMZs, and Campus does not support firewalls for getting the ARP table.

yes joe

for routers connected to this switch, i can see them green in campus topology map.

however if i search for windows PC in this switch, using user tracking or UT End Host Report i can't find any PC!!!.

so if i understand your answer, this is normal and there is no workaround ! isn't it?

Routers or switches?  End hosts connected to routers (even those with switch modules) will not show up in UT.  End hosts connected to switches should show up, but you may only be able to search for them by MAC address.

hi joe

no, i am not speaking about end hosts connected to routers. i am searching for our public servers connected to DMZ using VLANs in one discovered switch.

well, i tried seraching them by MAC address but i can't find any one!

Post a show run and show ver from one affected DMZ switch.  Also post the "show int status" and "show mac-address-table" outputs from this switch.  From the server, post the NMSROOT/campus/etc/cwsi/portsData.xml and vlanData.xml files.

attached file contains the requested infos for switch 10.151.50.1

oh yes! i forgot to change this in these switches.

thank you joe. you should change your avatar from devil to angel :-)

i was not able to attach portdata and vlandata details. so i publish them here:
