Feature History for Interfaces in Transparent Mode
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.
Bridge groups for transparent mode 8.4(1) If you do not want the overhead of security contexts, or want
to maximize your use of security contexts, you can group
interfaces together in a bridge group, and then configure
multiple bridge groups, one for each network. Bridge group
traffic is isolated from other bridge groups. You can
configure up to eight bridge groups of four interfaces each
in single mode or per context.
We introduced the following commands: interface bvi,
show bridge-group.
