Check if mac of 10.0.2.7 exists in FDB on all switches, also mac-learning is enabled on this port or vlan, and check overall MAC count on switch. Also there is a chance of hash collision, which leads to things thet some mac addresses cant be learned on switch FDB. 03.11.2017 11:20, Daniel пишет: > Hi there, > > > > i have some strange issues.
