- Regarding Speed on Port channel - Cisco Learning Network
What I meant to say is that the reflected speed should be of the individuals interfaces, in your scenario the speed of each physical interface (10Gbps) I think the actual speed of the portchannel in your scenario is 40Gbps not 10Gbps as it shows, but you can try to test it simply by downloading a big file from a server connected across the
- Switch Port Numbers - Cisco Learning Network
First, let try to understand what is GIG and Fa stand for? The GIG means the gigabit ethernet (1Gbps) and FA means FastEthernet (100 Mbps) Those are interface speed in the ethernet and some other examples are Ethernet (10 Mbps), TenGig (10Gbps) etc What is the meaning of fa0 0 or fa0 0 0?
- What is Cost? - Cisco Learning Network
One thing to note, in order to cater for the faster 10Gbps, 40Gbps and 100Gbps interfaces Cisco introduced the command auto-cost reference-bandwidth in order to reflect the real cost of the interface See this link for details
- EIGRP classic vs. wide metrics - Cisco Learning Network
Looking at EIGRP I got a bit confused on the fact that with classic metrics EIGRP can't differentiate between 10Gbps and 100Gbps but wide metrics can The formulas: Classic: 10^7 Bw x 256 Wide: 10^7 Bw x 65536 Why is it that in classic metrics the 256 is forgotten and we don't get 1 for 2 5Tbs and for wide metrics we use the 65536?
- How to calculate link cost? - Cisco Learning Network
as the page states, use spanning-tree pathcost method long to alter the different values and to accommodate speeds greater than 10gbps I might be mistaken, but I believe on older devices, speeds up to 10gbps were yielding the same output as 1gbps, and I don't recall how that was changed - nor was google being of any help on the topic
- Fragmentation of IP packets into Ethernet frames and defragmentation
So 10Gbps means we can transfer a max amount of 10Gbps of data over the link at a single time To see this in action issue commands such as show interface on your switch and when it shows you interface stats it will always show you the link load as a percentage, meaning the amount of data passing over the interface at one time
- Can cat5 cable handle 1Gbps connection if transmitted??
Hi Chandra, Actually Cat5 can "theoretically" can handle up to 100Mbps, but you can get it work with 1000Mbps if you make it shorter than 100 meters, instead Cat5e can handle 10 100 1000Mbps speeds The new generation of ethernet cables is Cat6, with this type you can handle up to 10Gbps, the main difference with Cat6 over Cat5e that it has internal separators between pair
- Difference between uplink and access (Downlink) port
As was mentioned in the thread you provided the link for, all ports have only one job--move traffic You could uplink this box on e1 1 (one of the 10Gbps ports), In a lab environment you might do exactly that since labs don't generally run the traffic volume a production network would expect and 40G cables might be harder to come by
