M4300 service port segregation issue?
Hi, I faced to a weird issue with M4300 service port, please refer to my diagram at bottom.
The BMC network has no problem before I deploy a new M4300-8x8f.
When I configured all port as diag...
Hi raytracy,
Welcome to the community! :)
Kindly answer the questions below:
a. What is the LAG state on the 10G LACP ports on both M4300-8X8F and Cisco switch?
b. On the M4300-8X8F, what is the Hash Mode of the LAG?
c. On the M4300-8X8F, is STP Mode enabled or disabled on the LAG? How about on the Cisco switch?
d. On the M4300-8X8F, are the 10G LACP ports set as tagged ports?
e. What is the current firmware version of the M4300-8X8F?
Let me share the forum thread below and it might help as reference:

a. Cisco side: LACP link state is ON, and both port are active member.
M4300 side: LACP mode enbled, both port Link status are Link up.
b. M4300 LACP Hash mode is: 6?) Src/Dest IP and TCP/UDP port fileds
Cisco side LACP Hash mode is: IP/Mac address
c. M4300 LACP set as Trunk allowed VLAN=1-4093, VLAN Tag=disable
Cisco set LACP as Trunk, VLAN 1-20 tagged, 21-4094 Inactive VLAN
BTW, if I blocked the VLAN 1 on Cisco side LACP by set it as Untagged (leave only 2-20 tagged), there is no problem to access all BMC IP, it seems cut off looping issue.
d. No, since I don't know how to set M4300 LACP as tagged, I have not configured it yet.
e. M4300 firmware version: 12.0.7.10, B1.0.0.11
Thanks!
Hi raytracy,
I inquired your concern to the higher tier of NETGEAR Support. I will post here once I got a feedback.

Just a follow-up. I tried to replicate your concern. Here below is the network setup I did based on the network diagram you have posted:
I created LACP between the M4300-28G-PoE+ and the M4300-52G using ports 9 & 10 of both switches. Then, I created VLAN 1010 on the GSM7252PS with ports 39-42 as untagged members. Then, I connected the OOB ports of the M4300-52G and M4300-28G-PoE+ to ports 39 & 40 of the GSM7252PS respectively. I created a DHCP pool for VLAN 1010 on the GSM7252PS (to resemble your BMC network).
Then, I connected a PC to port 42 of the GSM7252PS and was able to obtain an IP address as well as I'm able to get replies when I ping the OOB ports of both M4300-28G-PoE+ and M4300-52G switches. RSTP is enabled on all switches. The LACP ports on both M4300-28G-PoE+ and the M4300-52G are still up.
From the replication I did, the NETGEAR switches are working as expected since the ethernet ports and OOB are working independently.
