So it records the SVI mac address of the other switch in it's mac address table against the port that connects it to the other switch. the mac address of the other switches SVI and this will be entered into it's arp cache but this is not enough information because it still needs to know the physical port that the SVI mac address is reachable on. The switch will again arp for the mac address of the other switch. It gets the response and it can directly associate that mac address with it's 元 port in it's arp cache so it knows which port to send the packet out of.Ģ) SVIs. The switch will arp for the mac address of the other switch. This is because when you use SVIs a 元 switch has to make an additional step that a router does not.ġ) 元 ports. However if you modified your setup so that instead of using 元 ports you put both ports into the same vlan and then created 元 vlan interfaces (SVIs) on both switches for that vlan and used the IPs you currently have on the 元 ports then you would see entries in the mac address table. When it uses 元 routed ports it acts exactly like a router in that all the information it needs is in the same tables. With a 元 switch on the other hand it depends.
all the information it needs to forward the packet is in the IP routing table and the arp cache (technically it's usually CEF tables but we'll keep things simple). R2's MAC Address Table with MACs learnt on Gi2/1/1Ī router does not have a mac address table because it doesn't need one ie. R2's MAC Address Table for R1's MAC address Protocol Address Age (min) Hardware Addr Type Interface Success rate is 100 percent (5/5), round-trip min/avg/max = 1/4/9 ms Packet sent with a source address of 192.168.74.130 # If R2's ARP table already has an entry for R1's IP along with the exit interface,ĭoes R2 still need to do a MAC Address Table lookup?
# How is R2 able to ping R1 without having the R1's MAC in it's MAC Address Table? # R2 can ping R1 and vice versa successfully
# Routed link between R1 and R2, both are Layer 3 switches. Nook: Tap Nav.Hi guys - I have a network setup that I'm a bit confused about - it has to do with packet forwarding over a routed link.The wireless MAC address for your Echo can be found at the bottom of the Echo Setup screen in the Alexa app.Connect to the wireless network transmitted by your Echo device.

Depending on your device you may have to go on the manufacturer’s website or consult the manual to locate the MAC address. The examples below are for illustrative purposes only. How do I find the MAC address (Device ID)? Short for media access control address, a MAC address is a unique combination of six pairs of hexadecimal numbers separated by either dashes or colons with the purpose of identifying your device over a network such as the internet.
