Show mac address table synchronize

Otherwise, it has to be enabled manually. The following command sets the redundancy mode to SSO.

However, it should be SSO by default. Do show redundancy to see that it is SSO. If it comes up RPR,! This might be one of a pair of data center distribution switches, with the VSS pair being a server switch. And of course the distribution pair would be connected to each other. However, it can just as easily be configured as a layer 2 etherchannel or even an access port etherchannel. The layer three etherchannel gets configured just as it would on any other switch. At this point you can do anything you want from a simulation perspective.

Configure loopbacks with addresses and configure a routing protocol.

Through all of this I used 10 Gig interfaces with which to connect switches. A MEC can be built on the ports and be used to connect to servers. For a server connecting to a single vlan, the etherchannel would be configured as an access port.

However, for VM servers, it would be reasonable to connect using dot. In that case the MEC could be configured as a trunk. All of that is pretty well documented in the Cisco docs I referenced. Incidentally, had the upstream switch really have been a distribution switch, it might instead look like this.

Layer 2 discovery process

This command gets executed only once. Synchronizing MAC address tables across switches doesn't make any sense. Each switch maintains its own MAC address table. For instance, suppose you have Switch 1 and Switch 2 connected together of their ports 24, and MAC address If no frames from MAC address If you synchronize MAC address table across those two switches, then how would you propose to resolve the port conflict where The closest thing you could have is with switch stacks, where multiple switches are connected in a stack, and the stack looks like a single switch.

You configure the stack, not the individual switches, and things like STP and MAC address tables are done as if the stack was a single switch. Switches don't normally 1 sync MAC tables, they independently build them based on the Source MAC addresses and ingress ports of frames they see. Obviously the ports associated with those MAC addresses will be different.

Understanding MAC Address Synchronization in a Junos Fusion - TechLibrary - Juniper Networks

Active 4 months ago. Viewed 3k times. So, to avoid a duplicate mac scenario per access port, if the frame does make its way to a neighboring switch and gets stored, its shows up in the trunk port port 24 of the switch cam table? Is that how it can show up on both switches AND avoid a port conflict?
