New and Changed Features in Cisco NX-OS Release 4.0(1a)N1(1a) Send documentation comments to [email protected] Cisco Nexus 5010 Switch The Cisco Nexus 5010 is a 28-port switch. It is a 1RU, 10-Gigabit Ethernet, Cisco Data Center Ethernet, FCoE, and Fibre Channel switch providing more than 500-Gbps throughput with very low latency. It has the following features: • Twenty fixed 10-Gigabit Ethernet, Cisco Data Center Ethernet, and FCoE SFP+ ports. Eight of the twenty fixed ports support GE and 10GE speed. • One expansion module slot that can be configured to support up to 6 additional 10-Gigabit Ethernet, Cisco Data Center Ethernet, and FCoE SFP+ ports, up to 8 Fibre Channel switch ports, or a combination of 4 additional 10-Gigabit Ethernet, Cisco Data Center Ethernet, and FCoE SFP+ ports with 4 additional 1/2/4-Gbps Fibre Channel switch ports. • Serial console port and an out-of-band 10/100/1000-Mbps Ethernet management port. • 1+1 redundant, hot-pluggable power supplies. • 1+1 redundant, hot-pluggable fan modules to provide highly reliable front-to-back cooling. For additional information about the Cisco Nexus 5010 switch see the Cisco Nexus 5000 Series Hardware Installation Guide. New and Changed Features in Cisco NX-OS Release 4.0(1a)N1(1a) The new or changed features for this release are described in the following topics: • The shutdown lan Command, page 3 • The errdisable recovery cause pause-rate-limit Command, page 4 • Kickstart Break Sequence, page 4 The shutdown lan Command The DCBX protocol provides a capability to signal LAN Logical Link Status (LLS) to a CNA that is connected to the Cisco Nexus 5000 switch over an Ethernet interface. This signaling can be used by the bonding driver in the host to perform a failover to the standby link to the LAN. The shutdown lan command provides the LAN administrator with the capability to trigger an LLS-Down to the CNA. This operation can be performed without any impact to the SAN traffic on the Ethernet interface. When the shutdown lan command is configured on an Ethernet interface, all VLANs that are not enabled for FCoE are brought down on the interface. This in turn triggers the LLS-Down signal. If non-FCoE VLANs are brought down by other means (like vlan shutdown) they trigger LLS-Down signaling if the only VLANs active on an Ethernet interface are enabled for FCoE. switch(config)# interface Ethernet 1/1 switch(config-if)# shutdown ? force Enable/disable an interface lan Shut all LAN VLANs on interface switch(config-if)# [no] shutdown lan OL-16601-01 Cisco Nexus 5000 Series Release Notes, Release 4.0(1a)N1(1a) 3
