DETAILED STEPS
Purpose
Command or Action
Enters XR configuration mode.
configure
Example:
Step 1
RP/0/RP0/CPU0:router# configure
Enters subinterface configuration mode and specifies the
interface type, location, and subinterface number.
interface
{
TenGigE
|
Bundle-Ether
}
interface-path-id.subinterface
Step 2
Example:
• Replace the
interface-path-id
argument with one of
the following instances:
RP/0/RP0/CPU0:router(config)# interface TenGigE
0/2/0/4.10
• Physical Ethernet interface instance, or with an
Ethernet bundle instance. Naming notation is
rack
/
slot
/
module
/
port
, and a slash between values
is required as part of the notation.
• Ethernet bundle instance. Range is from 1 through
65535.
• Replace the
subinterface
argument with the
subinterface value. Range is from 0 through 4095.
• Naming notation is
interface-path-id.subinterface
, and
a period between arguments is required as part of the
notation.
Sets the Layer 2 encapsulation of an interface.
encapsulation dot1q
Example:
Step 3
RP/0/RP0/CPU0:router(config-subif)# encapsulation
dot1q 100
Assigns an IP address and subnet mask to the subinterface.
ipv4 address ip-address mask
Step 4
Example:
• Replace
ip-address
with the primary IPv4 address for
an interface.
RP/0/RP0/CPU0:router(config-subif)# ipv4 address
178.18.169.23/24
• Replace
mask
with the mask for the associated IP
subnet. The network mask can be specified in either
of two ways:
• The network mask can be a four-part dotted
decimal address. For example, 255.0.0.0 indicates
that each bit equal to 1 means that the
corresponding address bit belongs to the network
address.
• The network mask can be indicated as a slash (/)
and number. For example, /8 indicates that the
first 8 bits of the mask are ones, and the
corresponding bits of the address are network
address.
