New Software Supported
page 12 OmniSwitch 6600/7000/8800—Release 5.1.5.R04
CLI Command to Disable PoE Capacitor Detector
The following new command has been added to enable/disable capacitor detection for Power over Ether-
net (PoE) devices:
• lanpower capacitor-detection
In addition, the following new command has been added to display the current PoE capacitor detection
method:
• show lanpower capacitor-detection
Destination TCP Port ACL Enhancements
A special service group named DropServices has been added to OS software for all platforms that
improves performance with ACLs intended to drop traffic with specific destination TCP/UDP ports. See
documentation for configuration examples and details on this new enhancement.
A new trap has been added whereby a switch will send a trap when a single link in the aggregate group is
down or cannot join the aggregate grou
p.
DOS Attacks and Port Security
Enhanced port security and additional features to prevent DOS attacks. These include:
• Detect and prevent IP source address spoofing
• BPDU control Packets on defined sets of ports
• Designate a set of switch ports as user ports
• Dropping packets based on TCP/UDP destination port
• Prevent VRRP flapping under virus/worm attack
• Filter ICMP Echo PING packets on user ports
Dynamic Link Aggregation across OS6600 Stacks
Dynamic link aggregation groups can now be configured across multiple switches in an OS6600 stack.
Ethernet Enhancements
Half duplex mode on the OmniSwitch 7700/7800 OS7-ENI-FM-12 is now supported.
Generic UDP Relay
In addition to BOOTP/DHCP relay, generic UDP relay is now available on OmniSwitch 7700/7800/8800
switches. Using generic UDP relay, traffic destined for well-known service ports (e.g., NBNS/NBDD,
DNS, TFTP, TACACS) or destined for a user-defined service port can be forwarded to a maximum of 256
VLANs on the switch.
