Increased VLANs 7.0(5) Increased the following limits:
• ASA5510 Base license VLANs from 0 to 10.
• ASA5510 Security Plus license VLANs from 10 to 25.
• ASA5520 VLANs from 25 to 100.
• ASA5540 VLANs from 100 to 200.
Increased interfaces for the Base license on the
ASA 5510 7.2(2) For the Base license on the ASA 5510, the maximum
number of interfaces was increased from 3 plus a
management interface to unlimited interfaces.
Increased VLANs 7.2(2) VLAN limits were increased for the ASA 5510 (from 10 to
50 for the Base license, and from 25 to 100 for the Security
Plus license), the ASA 5520 (from 100 to 150), the ASA
5550 (from 200 to 250).
Gigabit Ethernet Support for the ASA 5510
Security Plus License 7.2(3) The ASA 5510 ASA 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.
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.
This feature is also supported on the ASA 5585-X.
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.
