CVE-2000-0764
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIntel Express 500 series switches allow a remote attacker to cause a denial of service via a malformed IP packet.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceIntel Express 500 series switches contain a vulnerability where malformed IP packets sent remotely can cause the device to become unresponsive, resulting in a denial of service. The vulnerability lies in how the switch processes specially crafted IP packets.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Intel Express 8100 hardware in your networkReview network asset inventory, switch port diagrams, or use SNMP/walk commands to query device sysDescr or sysObjectID. Log into the device console or web management interface and check the model name under system information or device status.Affected if The device model listed is Intel Express 8100 (any firmware version)
-
Confirm device is network-accessibleCheck if the switch has an IP address assigned to its management interface and is reachable over the network. Use ping, telnet, SNMP, or web access to verify connectivity.Affected if The device responds to network queries and is accessible on the network (remote attack vector)
-
Determine management interface exposureReview firewall rules, ACLs, or VLAN configurations that control access to the switch management interface. Check if the management IP is reachable from untrusted networks or the internet.Affected if The management interface is exposed to networks beyond your trusted internal segment
You are affected if an Intel Express 8100 switch is present in your environment and is network-accessible, as all versions of this device are vulnerable to remote denial of service via malformed IP packets.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataSince these are legacy devices from 2000 likely end-of-life with no vendor support, mitigate by network segmentation to limit exposure, implementing ACLs to restrict traffic sources, or replacing with modern switches that receive active security support.
