Hello
I have a Problem with an an ACE4710 Setup. Between my 2 Ace's there are Switches which don't Support Jumbo Frames -
Is there a way to configure the Interface on the ACE to an Standard MTU Sive (15xx)
I'm using SW-Version A3(2.7).

default MTU is 1500 bytes on an interface. i.e.
interface vlan 178
ip address 10.x.x.x 255.255.255.0
access-group input ALL
service-policy input MGMNT
service-policy input jim1
no shutdown
MR23100315-ACE01/Admin# show int vlan 178
vlan178 is up, VLAN up on the physical port
Hardware type is VLAN
MAC address is 00:23:8b:03:74:61
Mode : routed
IP address is 10.x.x.x netmask is 255.255.255.0
FT status is non-redundant
Description:not set
MTU: 1500 bytes
Last cleared: never
Last Changed: Sun May 22 13:37:09 2011
No of transitions: 3
Alias IP address not set
Peer IP address not set
Assigned on the physical port, up on the physical port
Previous State: Sun May 22 13:36:03 2011, VLAN not up on the physical port
Previous State: Thu May 19 15:10:11 2011, VLAN up on the physical port
8654836 unicast packets input, 2693257658 bytes
1 multicast, 0 broadcast
0 input errors, 0 unknown, 0 ignored, 0 unicast RPF drops
9672812 unicast packets output, 2671360745 bytes
0 multicast, 8914 broadcast
0 output errors, 0 ignored
you can change it with mtu command
MR23100315-ACE01/Admin(config)# int vlan 178
MR23100315-ACE01/Admin(config-if)# m?
mac-address mac-sticky mtu
MR23100315-ACE01/Admin(config-if)# mtu ?
<68-9216> MTU size in bytes
This is configured on the logical interfaces of the ace (vlan interfaces) not the physical gig ports.

Thanks, but this is not what I'm looking for. I want to change the MTU-Size on the Interface from 9216 to 1536.
GigabitEthernet Port 1/4 is UP, line protocol is UP
Hardware is ACE Appliance 1000Mb 802.3, address is 00:1b:24:5e:89:6c
MTU 9216 bytes
Full-duplex, 100Mb/s
COS bits based QoS is disabled
input flow-control is off, output flow-control is off
....
The added FT Vlan has also an MTU-Size from 1500.
Thanks
