I have a new Cisco SG200-26P set up with two LACP LAGs for the two servers I have running on the same VLAN, both bonded with IEEE 802.3ad Dynamic Link Aggregation and have a speed issue with the second LAG.
Port GE8 is enabled with auto negotiation but the operation speed is dropping to 100m.
I have check the port settings and found that the Neighbor Advertisement has dropped to 10 Half 10 Full 100 Half 100 Full.
In LAG Management this port is listed a standby member of LAG Group 2
This is resulting in a bond speed of 3000mb/s for LAG 2 instead of 4000mb/s
Ethtool for LAG 1

What can be the issue?
