set interface ip address [del] <interface> <ip-addr>/<mask> | [all].
Add an IP Address to an interface or remove and IP Address from an interface. The IP Address can be an IPv4 or an IPv6 address. Interfaces may have multiple IPv4 and IPv6 addresses. There is no concept of primary vs. secondary interface addresses; they're just addresses.
To display the addresses associated with a given interface, use the command '<em>show interface address <interface></em>'.
Note that the debug CLI does not enforce classful mask-width / addressing constraints.
An example of how to add an IPv4 address to an interface:
vpp# set interface ip address GigabitEthernet2/0/0 172.16.2.12/24
An example of how to add an IPv6 address to an interface:
vpp# set interface ip address GigabitEthernet2/0/0 ::a:1:1:0:7/126
To delete a specific interface ip address:
vpp# set interface ip address del GigabitEthernet2/0/0 172.16.2.12/24
To delete all interfaces addresses (IPv4 and IPv6):
vpp# set interface ip address del GigabitEthernet2/0/0 all

Add the 'ip4-source-and-port-range-check-rx' or 'ip4-source-and-port-range-check-tx' graph node for a given interface. 'tcp-out-vrf' and 'udp-out-vrf' will add to the RX path. 'tcp-in-vrf' and 'udp-in-vrf' will add to the TX path. A graph node will be inserted into the chain when the range check is added to the first interface. It will not be removed from when range check is removed from the last interface.
By adding the range check graph node to the interface, incoming or outgoing TCP/UDP packets will be validated using the provided IPv4 FIB table (VRF).
Example of graph node before range checking is enabled:
vpp# show vlib graph ip4-source-and-port-range-check-tx
Name Next Previous
ip4-source-and-port-range- ip4-drop [0]
Example of how to enable range checking on TX:

set interface ip table <interface> <table-id>.
Place the indicated interface into the supplied IPv4 FIB table (also known as a VRF). The FIB table must be created using "ip table add" already. To display the current IPv4 FIB table, use the command '<em>show ip fib</em>'. FIB table will only be displayed if a route has been added to the table, or an IP Address is assigned to an interface in the table (which adds a route automatically).

set ioam [trace] [pot] [seqno] [analyse].
This command is used to enable In-band OAM (iOAM) features on IPv6. '<em>trace</em>' is used to enable iOAM trace feature. '<em>pot</em>' is used to enable the Proof Of Transit feature. '<em>ppc</em>' is used to indicate the Per Packet Counter feature for Edge to Edge processing. '<em>ppc</em>' is used to indicate if this node is an '<em>encap</em>' node (iOAM edge node where packet enters iOAM domain), a '<em>decap</em>' node (iOAM edge node where packet leaves iOAM domain) or '<em>none</em>' (iOAM node where packet is in-transit through the iOAM domain). '<em>ppc</em>' can only be set if '<em>trace</em>' or '<em>pot</em>' is enabled.
Use '<em>clear ioam rewrite</em>' to disable all features enabled by this command. Use '<em>show ioam summary</em>' to verify the configured settings.
