Resolved! 4948 10GB Not working for some reason
So i recently got a great deal on a 4948 with the 10GB modules included. I have them installed correctly and purchased a 10GB OM3 LC-SC 1 meter fiber cable that connects the switch to my Mikrotik Router. So Mikrotik lists the SFP and connector type w...

I want to block a MAC address on a switch no matter which vlan the MAC belongs to. I saw similiar command as the following: mac address-table static 0050.3e8d.6400 vlan 12 dropHowever it requires a vlan parameter. How do I specify all vlans?
Does Cisco have a private mib to put a mac address into a blackhole so that the communication to the ip with the mac address can be blocked? A similiar MIB from Huawei is the HUAWEI-L2MAM-MIB and the related table is hwdbCfgFdbTable.What I want to do...
show mac address-table dynamic will display the vlan of the MAC. Is there an equivallent mib to get such information? I know the BRIDGE-MIB can get the MAC and the port from which the MAC is learnt. But it does not give the vlan the MAC belongs to.
