Caveats Send documentation comments to [email protected] Workaround: Before downgrading to the Cisco NX-OS 4.0(1a)N1(1) release, remove rules from the roles configuration such that a role does not have more than 67 rules. • CSCsv55655 Symptom: The Cisco Nexus 5000 Series switch Ethernet port is configured in the 1 G mode of operation using the speed 1000 command. It does not advertise and auto-negotiate the flow control configuration. As a result, the link peer does not learn about the capabilities of the Nexus 5000 Series switches and does not enable flow control at its end. Workaround: Disable auto-negotiation on the link peer and enable flow control for flow control to work over the link. • CSCsw39639 Symptom: When a rule that refers to a specific interface name (Ethernet 1/1) is entered in the role definition CLI, the command could hang. Type Ctrl-C to return to the CLI prompt. Workaround: Do not configure rules that refer to specific interfaces in the role definition CLI. • CSCsy09062 Symptom: This is an open caveat in 4.0(0)N1(2a) and 4.0(1a)N1(1) releases. After an upgrade or downgrade if the show startup security command is issued before performing a copy running-config startup-config, the security process could crash. Workaround: You can avoid a core dump by issuing a copy running-config startup-config command after an upgrade or downgrade and before issuing the show startup command. • CSCsy08516 Symptom: This is an open caveat in 4.0(0)N1(2a) and 4.0(1a)N1(1) releases. After an upgrade or a downgrade and when the system comes up, users are assigned a network-operator role by default. Workaround: To avoid the problem, reload the switch after an upgrade or a downgrade and after the system comes up. You can then perform the copy running-config startup-config operation to save the correct configuration. Resolved Caveats-Cisco NX-OS Release 4.0(1a)N1(1) This section lists the resolved caveats for this release. • CSCsy37432 Symptom: This is an open caveat in the Cisco NX-OS 4.0(0)N1(2a) release. On the 4.0(0)N1(2a) release if an RBAC role has more than 35 rules configured, show running-config and copy running-config cause the vshd process to core dump. Workaround: Before downgrading to the Cisco NX-OS 4.0(0)N1(2a) release, remove rules from the roles configuration such that a role does not have more than 35 rules. • CSCsy53275 Symptom: This is an open caveat in the Cisco NX-OS4.0(0)N1(2a) release. If there are 20 RBAC roles configured with 20 rules each, the RBAC feature becomes non-functional. Workaround: Do not configure more than 20 rules in each role. The feature works fine if the numbers of rules are limited to 10 per role. OL-16601-01 Cisco Nexus 5000 Series Release Notes, Release 4.0(1a)N1(1a) 19
