However, if the DHCP feature has been enabled, the DHCPv6 relay agent is automatically enabled, even if no DHCPv6 server address is configured on the device.\r\n\r\nIf the DHCP feature is enabled, the DHCPv6 relay agent may be manually disabled using the no ipv6 dhcp relay configuration command at the device CLI.\r\n\r\nTo determine if the DHCPv6 relay agent is enabled, use the show run all | include \"^ipv6 dhcp relay\" command at the device CLI. If the command returns output, the DHCPv6 relay agent is enabled, as shown in the following example:\r\n\r\n\r\nswitch# show run all | include \"^ipv6 dhcp relay\"\r\nipv6 dhcp relay\r\n\r\nTo determine if at least one IPv6 address is configured on the device, use the show ipv6 interface brief command at the device CLI, as shown in the following example:\r\n\r\n\r\nswitch# show ipv6 interface brief\r\nIPv6 Interface Status for VRF \"default\"(1)\r\nInterface        IPv6 Address/Link-local Address           Interface Status\r\n                                                           prot/link/admin\r\nEth1/50          2001:db8::1                               up/up/up\r\n               fe80::a678:6ff:fed1:3e45",

Customers with service contracts that entitle them to regular software updates should obtain security fixes through their usual update channels.\r\n\r\nCustomers may only install and expect support for software versions and feature sets for which they have purchased a license. By installing, downloading, accessing, or otherwise using such software upgrades, customers agree to follow the terms of the Cisco software license:\r\nhttps://www.cisco.com/c/en/us/products/end-user-license-agreement.html [\"https://www.cisco.com/c/en/us/products/end-user-license-agreement.html\"]\r\n\r\nAdditionally, customers may only download software for which they have a valid license, procured from Cisco directly, or through a Cisco authorized reseller or partner. In most cases this will be a maintenance upgrade to software that was previously purchased. Free security software updates do not entitle customers to a new software license, additional software feature sets, or major revision upgrades.\r\n\r\nThe Cisco Support and Downloads page [\"https://www.cisco.com/c/en/us/support/index.html\"] on Cisco.com provides information about licensing and downloads. This page can also display customer device support coverage for customers who use the My Devices tool.\r\n\r\nWhen considering software upgrades [\"https://sec.cloudapps.cisco.com/security/center/resources/security_vulnerability_policy.html#fixes\"], customers are advised to regularly consult the advisories for Cisco products, which are available from the Cisco Security Advisories page [\"https://www.cisco.com/go/psirt\"], to determine exposure and a complete upgrade solution.\r\n\r\nIn all cases, customers should ensure that the devices to be upgraded contain sufficient memory and confirm that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, customers are advised to contact the Cisco Technical Assistance Center (TAC) or their contracted maintenance providers.\r\nCustomers Without Service Contracts\r\nCustomers who purchase directly from Cisco but do not hold a Cisco service contract and customers who make purchases through third-party vendors but are unsuccessful in obtaining fixed software through their point of sale should obtain upgrades by contacting the Cisco TAC: https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html [\"https://www.cisco.com/c/en/us/support/web/tsd-cisco-worldwide-contacts.html\"]\r\n\r\nCustomers should have the product serial number available and be prepared to provide the URL of this advisory as evidence of entitlement to a free upgrade.\r\nCisco NX-OS Software\r\nTo help customers determine their exposure to vulnerabilities in Cisco NX-OS Software, Cisco provides the Cisco Software Checker [\"https://sec.cloudapps.cisco.com/security/center/softwarechecker.x\"]. This tool identifies any Cisco security advisories that impact a specific software release and the earliest release that fixes the vulnerabilities that are described in each advisory (\u201cFirst Fixed\u201d). If applicable, the tool also returns the earliest release that fixes all the vulnerabilities described in all the advisories that the Software Checker identifies (\u201cCombined First Fixed\u201d).\r\n\r\nTo use the tool, go to the Cisco Software Checker [\"https://sec.cloudapps.cisco.com/security/center/softwarechecker.x\"] page and follow the instructions. Alternatively, use the following form to search for vulnerabilities that affect a specific software release. To use the form, follow these steps:\r\n\r\nChoose which advisories the tool will search\u2014only this advisory, only advisories with a Critical or High Security Impact Rating (SIR) [\"https://sec.cloudapps.cisco.com/security/center/resources/security_vulnerability_policy.html#asr\"], or all advisories.\r\nChoose the appropriate software.\r\nChoose the appropriate platform.\r\nEnter a release number\u2014for example, 7.0(3)I7(5) for Cisco Nexus 3000 Series Switches or 14.0(1h) for Cisco NX-OS Software in ACI mode.\r\nClick Check.\r\n\r\n     Only this advisory All Critical and High advisories All advisories  Cisco NX-OS Software Cisco NX-OS Software in ACI Mode  Any Platform MDS 9000 Series Multilayer Switches Nexus 1000V Series Switches Nexus 3000 Series Switches Nexus 5000 Series Switches Nexus 6000 Series Switches Nexus 7000 Series Switches Nexus 9000 Series Switches\r\n\r\n\r\n\r\n\r\n Additional Resources\r\nFor help determining the best Cisco NX-OS Software release for a Cisco Nexus Switch, see the following Recommended Releases documents.
