DHCP snooping
3 TopicsSimple port security
Hello there my name is Peter. I would like a function to be added to these series of switches that prevents a rouge user to connect equipment to any port and gain access to the network or disturb/bring it down with maybe a CAM overflow attack. It would work such that if an unreasonable amount of connection attempts with different mac adresses occurs - it disables that port or something. A better idea would be to use DHCP snooping in the switch so we could enter allowed MAC and IP adresses in the router instead. I know that switches like GS108Tv2 probably supports this however there is no GS105T small 5-port version available so I am forced using GS105Ev2 instead which is a nice little switch indeed. If DHCP snooping is too complex maybe you could add a little menue instead so we could enter a couple of MAC adresses allowed on each port. Thanks sincerely Peter15KViews1like1CommentDHCP Snooping Block DNS Packet
Hi, I've just encounter an issue with my GS724TPv2. As soon as I enabled the DHCP Snooping mode, I cant make dns resolving. Trusted Inferfaces are ok, and I retrieve an Ip from my dhcp server (which is the same as my dns server). I can ping, go to web servers (with their ips). If I turn off DHCP snooping mode, it works again (mac address validation didnts seem to have an impact), I can see my computer informations in the dynamic binding configuration screen. I have 3 724tp connected with LACP, i tried with one switch alone, no results I have DHCP snooping/filtering set up on my other switches (GS724T no POE) and I dont have this issue. If anyone has an idea (misconfiguration, bug,...) ? Thanks a lotSolved4.5KViews0likes8CommentsDHCP Snooping missing on M5300-52G3
