CSMA/CD - Carrier Sense Multiple Access/Collision Detect.
10Base2 and 10Base5 - typically 10 MB/Half duplex. This is where there is a common tx/rx medium that all connected devices share. Collisions are normal, hosts listen and wait for open time to broadcast/send packets over the wire. This is what a legacy HUB does.
A Switched network allows each connected host/device to have a dedicated slice of the ethernet pie and collisions should theoretically never occur in FULL DUPLEX operation. However a switch port/interface configured as half duplex will electricaly function like it is a CSMA/CD Hub port and will normally accumulate collision errors, but ONLY on that port/interface, all other switch ports/interfaces running full duplex will never see these errors/conditions.
Question We run asr9001 with XR 6.1.3, and we have a very long delay to
login w/ SSH 1 or 2 to the device compare to IOS device. After
investigation, the there is 1s delay between the client KEXDH_INIT and
the server (XR) KEXDH_REPLY. After debug ssh serv...
Introduction The purpose of this document is to demonstrate the Open
Shortest Path First (OSPF) behavior when the V-bit (Virtual-link bit) is
present in a non-backbone area. The V-bit is signaled in Type-1 LSA only
if the router is the endpoint of one or ...
Hi, I am seeing quite a few issues with patch install and wanted to
share my experience and workaround to this. Login to admin via CLI, then
access root with the “shell” command Issue “df –h” and you’ll probably
see the following directory full or nearly ...
