I have an Cisco ASA 5505 connected to a provider's Nortel Baystack Switch. Apparently when high traffic hits the interface the firewall hangs. At 100 Mbps Full-Duplex hardcoded the ASA was showing high overrun rates and dropping traffic to devices on the network. However, after removing the hard-coding the operation is apparently normal. Interface negotiated at 100Mbps Full Duplex. I have also upgraded the IOS to 8.22. Anyone ever had a similar issue?

ASA and Nortel Switch

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
