I have a following network topology: C3750G-12S[Gi1/0/12] <-> [ge-0/0/0]Juniper M10i[ge-1/0/0] <-> [Po1]Cisco 4506[Gi2/6] <-> [Gi1/0/1]C3750G-12S
At the moment all of those interfaces have different MTU settings. The Cisco 4506 GBIC interface has the smallest(1500 bytes) and M10i SFP interface ge-1/0/0 has currently the largest(9192 bytes). All other interfaces are somewhere in between. Is it possible, that changing the data link layer MTU value could cause an outage or traffic degradation(it's a live connection with ~10Mbps traffic on both directions)? Is it a best practise to use the largest possible value on all interfaces or find out the largest supported MTU on the circuit and use this for all the interfaces? regards, martin _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
