Detailed Steps
What to Do Next
(Optional) Configure IPv6 addressing. See the “Configuring IPv6 Addressing” section on page 8-11 .
Configuring IPv6 Addressing
This section describes how to configure IPv6 addressing. For more information about IPv6, see the
“Information About IPv6 Support” section on page 21-9 and the “IPv6 Addresses” section on page B-5 .
This section includes the following topics:
Command Purpose
Step 1 For the ASA 5510 and higher:
interface {{redundant number |
port-channel number |
physical_interface}[.subinterface] |
mapped_name}
For the ASA 5505:
hostname(config)# interface vlan number
Example:
hostname(config)# interface vlan 100
If you are not already in interface configuration mode, enters
interface configuration mode.
The redundant number argument is the redundant interface ID,
such as redundant 1.
The port-channel number argument is the EtherChannel interface
ID, such as port-channel 1.
See the “Enabling the Physical Interface and Configuring
Ethernet Parameters” section for a description of the physical
interface ID.
Append the subinterface ID to the physical or redundant interface
ID separated by a period (.).
In multiple context mode, enter the mapped_name if one was
assigned using the allocate-interface command.
Step 2 mac-address mac_address
[standby mac_address]
Example:
hostname(config-if)# mac-address
000C.F142.4CDE
Assigns a private MAC address to this interface. The mac_address
is in H.H.H format, where H is a 16-bit hexadecimal digit. For
example, the MAC address 00-0C-F1-42-4C-DE is entered as
000C.F142.4CDE.
The first two bytes of a manual MAC address cannot be A2 if you
also want to use auto-generated MAC addresses.
For use with failover, set the standby MAC address. If the active
unit fails over and the standby unit becomes active, the new active
unit starts using the active MAC addresses to minimize network
disruption, while the old active unit uses the standby address.
Step 3 mtu interface_name bytes
Example:
hostname(config)# mtu inside 9200
Sets the MTU between 300 and 65,535 bytes. The default is 1500
bytes.
Note When you set the MTU for a redundant or port-channel
interface, the ASA applies the setting to all member
interfaces.
For models that support jumbo frames, if you enter a value for any
interface that is greater than 1500, then you need to enable jumbo
frame support. See the
“Enabling Jumbo Frame Support
(Supported Models)” section on page 6-32 .
