Interfaces	● 32 fixed ports configurable as 1 and 10 Gigabit Ethernet and FCoE or 8/4/2/1-Gbps native Fibre Channel; additional interfaces through one expansion module ● Expansion modules ● 16-port 1 and 10 Gigabit Ethernet and FCoE module ● 8-port 8/4/2/1-Gbps Fibre Channel plus 8-port 1 and 10 Gigabit Ethernet and FCoE module ● Unified port module consisting of 16 ports configurable as 8/4/2/1-Gbps Fibre Channel or 1 and 10 Gigabit Ethernet and FCoE ● 4-port QSFP expansion module ● 12-port 10G BASE-T module (Cisco Nexus 5596T only) ● Layer 3 module (Cisco Nexus 5596UP and 5596T only; one per system) ● Layer 3 daughter card (Cisco Nexus 5548P and 5548UP only; one per system) ● Extension through the Cisco Nexus 2000 Series
Physical Specifications
SFP+ Optics	Cisco Nexus 5500 platform supports 10 Gigabit Ethernet SFP+ copper Twinax cables for short distances and SFP+ optics (10GBASE-SR, 10GBASE-LR, 10GBASE-ER, GLC-ZX-SM and Cisco Nexus 2000 Series Fabric Extender Transceiver [FET-10G]) for longer distances. SFP+ has several advantages compared to other 10 Gigabit Ethernet connectivity options: ● Small 10 Gigabit Ethernet form factor ● Optical interoperability with XENPAK, X2, and XFP interface types ● Low power consumption ● Hot-swappable device ● Cisco Nexus 5500 platform products support 8-Gbps Fibre Channel-compatible SFP+ for native Fibre Channel connectivity options; 8-Gbps Fibre Channel-compatible short-reach and 10-km long-reach SFP transceiver modules operate at 8/4/2 Gbps and are supported in the 8?Gbps-capable native Fibre Channel ports on expansion modules and unified ports
Physical (height x width x depth)	1.72 x 17.3 x 29.5 in. (4.4 x 43.9 x 74.9 cm)
Operating temperature	32 to 104°F (0 to 40°C)
Nonoperating (storage) temperature	-40 to 158°F (-40 to 70°C)
Humidity	5 to 95% (noncondensing)
Altitude	0 to 10,000 ft (0 to 3000m)
Weight	35 lb (15.88 kg)

Q&A

Q How is the loop actually detected?

A Forwarding Manager (FWM) has a mechanism to count the number of MAC-move-backs and weigh them based on the number of times the MAC address moves. It determines the total MAC-move-backs count (switch-wide across all VLANs, MACs, and interfaces), declares the %FWM-2-STM_LOOP_DETECT, and disables learning to protect FWM in loopy conditions.

Q What do you do when a Nexus 5000 switch displays the "FWM-2-STM_LOOP_DETECT" message in the log?

A This message indicates that the switch receives frames with the same source MAC address on these two interfaces and that the swtich learns the same MAC address on these interfaces at a very high speed. The switch detects this as a loop. The switch disables MAC address learning in order to protect its control plane. This is implemented on all VLANs even if the loop occurred on only one VLAN.
