Hello Communality,
I need you help!
here is the goal: connect SAN and vmware ESXi by iSCSI via cisco3750g.
on cisco I'm using a separated vlan for iSCSI traffic.
So after turning on the JumboFrames on cisco ( system mtu jumbo 9000 > reload) I was trying to test it using PING command from the switch without success :-(
#show system mtu
System MTU size is 1500 bytes
System Jumbo MTU size is 9000 bytes
System Alternate MTU size is 1500 bytes
Routing MTU size is 1500 bytes
#ping 192.168.0.21 size 9000 df-bit repeat 1
Type escape sequence to abort.
Sending 1, 9000-byte ICMP Echos to 192.168.0.21, timeout is 2 seconds:
Packet sent with the DF bit set
.
Success rate is 0 percent (0/1)
#show int gi1/0/3 mtu
Port Name MTU
Gi1/0/3 iSCSI 9000
#show vlan mtu
VLAN SVI_MTU MinMTU(port) MaxMTU(port) MTU_Mismatch
---- ------------- ---------------- --------------- ------------
1 1500 9000 9000 No
192 1500 9000 9000 No
#show ru int gi1/0/3
Building configuration...
Current configuration : 108 bytes
!
interface GigabitEthernet1/0/3
description iSCSI
switchport access vlan192
switchport mode access
end
thanks!

Hello
Did you reload the switch?

sure! I did reload the switch after MTU set to 9000

Hello
Does the interface need to be an access port or trunk?
