Feature History for Interfaces in Routed Mode
Gigabit Ethernet Support for the ASA 5510
Security Plus License
7.2(3) The ASA 5510 now supports GE (Gigabit Ethernet) for port
0 and 1 with the Security Plus license. If you upgrade the
license from Base to Security Plus, the capacity of the
external Ethernet0/0 and Ethernet0/1 ports increases from
the original FE (Fast Ethernet) (100 Mbps) to GE (1000
Mbps). The interface names will remain Ethernet 0/0 and
Ethernet 0/1. Use the speed command to change the speed
on the interface and use the show interface command to see
what speed is currently configured for each interface.
Native VLAN support for the ASA 5505 7.2(4)/8.0(4) You can now include the native VLAN in an ASA 5505
trunk port.
We introduced the following command: switchport trunk
native vlan.
Jumbo packet support for the ASA 5580 8.1(1) The Cisco ASA 5580 supports jumbo frames. A jumbo
frame is an Ethernet packet larger than the standard
maximum of 1518 bytes (including Layer 2 header and
FCS), up to 9216 bytes. You can enable support for jumbo
frames for all interfaces by increasing the amount of
memory to process Ethernet frames. Assigning more
memory for jumbo frames might limit the maximum use of
other features, such as access lists.
We introduced the following command: jumbo-frame
reservation.
Increased VLANs for the ASA 5580 8.1(2) The number of VLANs supported on the ASA 5580 are
increased from 100 to 250.
IPv6 support for transparent mode 8.2(1) IPv6 support was introduced for transparent firewall mode.
Support for Pause Frames for Flow Control on
the ASA 5580 10 Gigabit Ethernet Interfaces
8.2(2) You can now enable pause (XOFF) frames for flow control.
We introduced the following command: flowcontrol.
