What is a unified port?
Unified ports are ports on the 6200 series fabric interconnect that can be configured to carry either Ethernet or Fibre Channel traffic. These ports are not reserved. They cannot be used by a Cisco UCS domain until you configure them.
What are SFP ports called?
mini-Gigabit interface converter
In many cases, SFP ports are also known as mini-Gigabit interface converter (GBIC) modules, as they have replaced the older GBIC transceivers.
What are SFP ports used for on a switch?
SFP ports enable Gigabit switches to connect to a wide variety of fiber and Ethernet cables in order to extend switching functionality throughout the network. Small form-factor pluggable, or SFP, devices are hot-swappable interfaces used primarily in network and storage switches.
What is Unified Port in Nexus?
Cisco Nexus unified ports allow you to configure a physical port on a Cisco Nexus device switch as a 1/10-Gigabit Ethernet, Fibre Channel over Ethernet (FCoE), or 2-, 4-, 8-Gigabit native Fibre Channel port. Unified device—Runs LAN and SAN services on the same platform switch.
What is port channel in Cisco UCS?
An uplink Ethernet port channel allows you to group several physical uplink Ethernet ports (link aggregation) to create one logical Ethernet link to provide fault-tolerance and high-speed connectivity. In Cisco UCS Manager, you create a port channel first and then add uplink Ethernet ports to the port channel.
What type of connector is used with an SFP port?
In a nutshell, a combo SFP port is regarded as a single interface with dual front ends, i.e. an RJ-45 connector and an SFP (Small Form Pluggable) module (also called Mini-GBIC) connector.
What is ASIC in Nexus?
The ASIC is the powerhouse of the Nexus switch. The ASIC, or Application Specific Integrated Circuit, is a special purpose sillicon chip. The ASIC achieves high forwarding speeds as packets pass through the forwarding plane. An ASIC in a general sense is not unique to networking.
What is ASIC in Cisco switch?
An ASIC stands for “Application Specific Integrated Circuit”. As the name suggests, an ASIC is a specialized piece of hardware circuitry designed to perform a particular operation in a highly efficient way.
What’s the difference between SFP and SFP + ports?
SFP ports are found in a range of devices, from Ethernet switches to routers, NIC cards and firewalls. Small form factor pluggable specification is based on IEEE802.3 and SFF-8472. SFP and SFP+ transceivers are virtually identical in size and appearance.
What kind of cable is used for gigabit SFP?
When the SFP port is inserted in 1G SFP with electrical port, the network cable (Cat5e/Cat6/Cat7 cable) must be used for data transmission. Whereas, when the SFP port is plugged in Gigabit SFP with optical port, fiber jumpers (LC fiber) need to support fiber connections.
Can a twisted line port be used for a SFP slot?
You can use a pair of twisted-line ports or SFP slots for combination port pairs, but not at the same time. If you connect a combination port pair to a network device with a twisted port and an SFP slot, the SFP slot is preferred and the twisted pair port is blocked.
How many SFP ports are in a 1G ring?
The uplink modules are spare part you buy them separately. The two devices that join the 1G ring with the 10G links upstream should be models with 12 or 24 GE SFP ports and have in addition the C3KX-NM-10G uplink module. All the devices in the ring 1G can have the uplink module C3KX-NM-1G with 4 SFP ports each.
