We’re running in a problem with 2 new Catalyst 4507-E switches equiped with WS-X4648-RJ45V-E linecards being taken into use. POE is not used. Some of the connected equipment is 70 to 80 meter away from the switch. The used CAT6 cabling is verified to be ok. Connection speed is Gigabit/s. The connected devices show continous RX errors and the switch debug info shows the links dropping away every now and then.
Replacing the switch with a Catalyst 3750-E or a low cost 8 port SLM2008 solves the issues.
Current conclusion points into the direction that the WS-X4648-RJ45V-E linecard is not able to drive CAT6 cables of this length but this is hardly believeable. So I am looking for other possible causes and how to remedy the situation. All help more than appreciated.
when we stack two switches ( e.g. C9300) what is max speed of such stack cable?The idea is: will the speed of stack cable bigger than ~20 Gb/s which could be achieved by etherchannel of two 10Gb/s ports.
Hi all, The Catalyst 9200L switches has a non-blocking architecture? I have found at documentations that Catalyst 9200 uses UADP 2.0 mini ASIC which has up 100G total bandwidth. https://community.cisco.com/t5/networking-blogs/uadp-the-...
Hi guys!I need help to understand how access points works with VLANs. I created 2 VLANs in Packet Tracer, vlan 10 (HR department) and vlan 20 (Sales department) namely and i also have an access point in the network. So what i want to know is ...
I have a 2960x-48fpd-l running 15.2.2E3 connected to a 3702 AP. Port config pasted below. The AP is in local switching mode so all the clients get dropped off at the switch - hence the trunk and multiple vlans because of the various ssid's and radius over...
