TitleNeed to know whether we are using any Jumbo frames on a VDX8770
Question
How to I know whether we are using jumbo frames on a VDX8770 switch
Environment
  • VDX8770
  • NOS 5..2.00 and higher
Answer
Issue show running-config interface gigabitethernet x/x/x mtu

Example:
 
CORE1# show running-config interface GigabitEthernet 1/2/1 mtu
interface GigabitEthernet 1/2/1
 mtu 2500   <------

DGS-CP-CORE1#  show interface gigabitethernet 1/2/1
GigabitEthernet 1/2/1 is up, line protocol is down (link protocol down)
Hardware is Ethernet, address is 0027.f8e5.4ae6
    Current address is 0027.f8e5.4ae6
Pluggable media not present
