Hello the HUB !
š
I am getting trouble with MAC to IP resolution on customer's NAC installation.
There are many X440-G2's stacks with 22.4.1.4-patch1-2 EXOS and there is nodealias configured on all access ports.
On some ports IP resolution works fine like this:
code:Slot-1 PPD03.9 # sh nodealias ports 5:8
Port MAC Address Alias ID Time Last Learned VID Protocol Source IP
----- ----------------- ---------- ------------------- ---- -------- ---------------
5:8 a4:14:37:5c:b1:6a 38 01-28-2019 13:11:47 4000 ip 192.168.72.82
5:8 a4:14:37:5c:b1:6a 78 01-28-2019 13:11:58 4000 mdns
5:8 a4:14:37:5c:b1:6a 151 01-28-2019 13:56:30 4000 ssdp
5:8 a4:14:37:5c:b1:6a 162 01-28-2019 14:25:33 60 ip 192.168.72.82
5:8 a4:14:37:5c:b1:6a 218 01-28-2019 14:28:44 60 ssdp
While on the others within the same stack it looks like below:
code:Slot-1 PPD03.10 # sh nodealias ports 5:19
Port MAC Address Alias ID Time Last Learned VID Protocol Source IP
----- ----------------- ---------- ------------------- ---- -------- ---------------
5:19 a4:14:37:5c:af:48 6 01-28-2019 13:11:00 4000 ip 192.0.0.64
5:19 a4:14:37:5c:af:48 55 01-28-2019 13:11:50 4000 ip 192.168.72.98
5:19 a4:14:37:5c:af:48 122 01-28-2019 13:12:09 4000 mdns
5:19 a4:14:37:5c:af:48 152 01-28-2019 14:00:30 4000 ssdp
5:19 a4:14:37:5c:af:48 209 01-28-2019 14:28:10 60 ip 192.168.72.98
5:19 a4:14:37:5c:af:48 234 01-28-2019 14:29:26 60 ssdp
I have two IPs for the same MAC and I have "Unable to resolve IP address from multiple IPs" state description in End-Systems table.
End-systems are Hikvision IP cameras, 192.0.0.64 is their default IP address, which should disappear after correct IP is set on camera.
Do you think it could be the bug in the camera firmware ? Or should I check something in my config ?
All I have in my stack config regarding nodealias configuration is:
enable nodealias ports x:yy
on all access ports.
By the way:
How the info for nodealias is collected and updated? Each time the device is reautheticated ?
Is there anything like nodealias aging ?
REGARDS, Robert
