Re: MTU change in procurve

hi
on Procurve switch 10/100 ports default mtu 1522bytes and not change

because support jumbo frame on switch 1Gbps and 10Gbps ports change the mtu limit with jumbo frame enable commad.

-------------------------------------------
Q: Are Jumbo frames supported on the ProCurve Switch 5400zl and 3500yl series switches?
Yes. Ports operating at 1 Gbps or 10 Gbps speeds accept forward packets of up to 9220 bytes (including four bytes for a VLAN tag) when configured for jumbo traffic. Note that on ports operating at 10 Mbps or 100 Mbps, the Maximum Transmission Unit (MTU) is fixed at 1522 bytes. The switch drops any inbound packets larger than the MTU allowed on a port.
-------------------------------------------
jumbo frame enable
jumbo
â   [no] vlan VLAN-ID jumbo
Usage: [no] jumbo
Description: Labels this VLAN as a Jumbo VLAN, allowing you to pass
packets up to 9220 bytes in size.
This is a VLAN context command. It can be called directly
from the VLAN context or follow the 'vlan VLAN-ID'
command.

Re: MTU change in procurve

Is there any method to check the MTU size, even they fixed MTU size to 1522.

And, if possible, can I do the check by iMC, due to there are a lot of devices in our environment.
