Requesting MTU value from DHCP server is explicitly disabled using a configuration similar to the following: tmsh modify sys management-dhcp sys-mgmt-dhcp-config request-options delete { interface-mtu }. But if DHCP send MTU value in its reply, this MTU will be configured on BIG-IP management interface.
BIG-IP accepts the MTU value provided.
DHCP server ignoring option sent by BIG-IP DHCP client.
1. Add supersede interface-mtu 1500; to interface "mgmt" section of the /etc/dhclient.conf file. 2. Restart dhclient.
dhclient now honors 'interface-mtu' request-options.
