CISCO MAC ADDRESS TIMEOUT SWITCH PORT VERIFICATION
Configuration and Verification Task 1: For reference information on configuring hostnames, please refer to earlier labs. Verify your configuration with port-security commands in Cisco IOS. Specifies the PGM multicast host interface In the event of port security configuration violations, where more than one MAC address is observed on that interface, the switch should shut the interface down. Specifies the 10-Gigabit Ethernet interface Specifies the telecom bus clock controller Specifies the port group interface number. Specifies the Ethernet channel of interfaces. Specifies the multilink Frame Relay bundle Specifies the long-reach Ethernet interface Specifies the filter group interface number. Specifies the auto-template interface number. Specifies the asynchronous interface number. Lists the various interfaces to choose ACL To clear platform-specific feature managerĬonfiguration commands, use the clear platform feature-manager command.Ĭlear platform feature-manager Syntax Description Or configures a static MAC address with IGMP snooping disabled forĭisplays addresses in the MAC address table MAC address with a particular switched port interface.Īssociates a restricted static address with aĪssociates a secure static address with aĪdds static entries to the MAC address table Keeps dynamic MAC addresses in memory before discarding.Īssociates a permanent unicast or multicast (other than IP or IPX) of the entries to clear.

CISCO MAC ADDRESS TIMEOUT SWITCH PORT UPGRADE
Switch model WS-C3850-48P running version 03.02.02.SEĪnyone any ideas ? Upgrade the software ? The config on the switch ports is straight forward and is the same on all the ports. Likewise I'm able to ping the end devices connected to the ports. When my laptop was connected to both ports I was able to get a DHCP address and connect to the rest of the network without issues. I then plugged it into one of the ports having the issue and I could no longer see the mac address. I plugged my laptop into a working port and I could see the mac addres. The ports affected are spread over both switches.
The stack isn't displaying mac learned on certain ports. Having a small issue at the moment with a 2 * 3850 switch stack.
