Hello,
i had an issue today while doing some LAB.
ACS PC, R1 f0/1 and IPS Mgmt interface where all in VLAN 10,
Switchports connected to these devices where showing UP UP.
I was able to ping IPS and R1 F0/1 from each other but ACS was not reachable
from any of the two devices.
ACS IP = 10.11.11.25/24 (VM Ware interface) = Vlan 10
R1 f0/1 = 10.11.11.1/24 = VLan 10
IPS Mgmt = 10.11.11.15 = vlan 10
when i did some research on this, i foung that Switch mac address table was
showing some MAC learned dynamically on switch's port f0/14 where this ACS PC
was connected. The MAC address in the mac table on switch was different then
the MAC assigned to VMware interface of the ACS.
and when i checked the arp table on R1 it din't had any arp entry for ACS PC.
Ping to loopback 127.0.0.1 from ACS was successfull
Ping to its own IP (10.11.11.25) was successfull
but ping from ACS PC to any other device failed.
Could anyone please let me know what could be the issue?
