We have been running in to a problem over the last year where random computers each morning are taking approx 15 minutes to obtain an IP address. It is completely random and is
Review common issues when you run or scale large AKS clusters. The article includes troubleshooting tips for resolving these issues.
HELLO, WE HAVE slow internet connections on all VLANs that are created on the MS425 core switches i need for help
Recently, we''ve had some complaints about slowness accessing some resources in our virtualized environment. This has caused me to take a
Guest Post: Small buffers could result in excessive packet loss and underutilized output links. How are high-end routing ASICs addressing this
Hi, I have 1 x c2960S and 3 x 2960X stacking together. All switches have the SDM preference at lanbase and same IOS version. The stack port-speed at 10 for every switches. I have
When pinging a server from a PC (Subnet 2) which is directly connected to the Core Switch the response time is about 10 ms (PC --> Core-Switch --> Server). It seems to me that the
Master and Sub Switches are Stacked, Primary and Secondary Masters linked by Fibre Optic. For some reason it seems to take atleast 30 seconds for clients to be allocated with an IP
A. Switch Technology (ROSETTA) The core of the SLINGSHOT interconnect is the ROSETTA switch, providing 64 ports at 200 Gb/s per direction. Each port uses four lanes of 56 Gb/s
Hi all, I have an issue with my company network. in core switch one port use 70 to 80% from internet. other ports share the 20% I try to shutdown this port and i noticed that the issue is not

This document describes how to troubleshoot slow Dynamic Host Configuration Protocol (DHCP) address allocation or intermittent DHCP address
Hier sollte eine Beschreibung angezeigt werden, diese Seite lässt dies jedoch nicht zu.
Get a closer look at core switches: the nerve centers of network infrastructure that enhance performance and facilitate growth.
Every extra step of switching is an extra delay. No matter how fast your core is, it''s still processing. That said, at only 2GB a day you won''t notice it, and I''m sure that 300 port switches don''t exist. Now if you
Greetings again to the well of knowledge I have two (that I''ve identified at this point) specific IP addresses where attempts to get to the shares on my file server are excruciating slow or
Merged Switch Allocation and Traversal in Network-on-Chip Switches Giorgos Dimitrakopoulos, Emmanouil Kalligeros, Member, IEEE, and Kostas Galanopoulos, Student Member, IEEE
On a Layer 3 switch, when the IP route is not known, the switch hardware punts (sends) IP packets to the CPU for IP routing. Punted packets are handled at the interrupt level and can cause
Switch Restart (Troubleshooting Step): As a troubleshooting step, consider performing a controlled restart of the core switches (MS425) during a maintenance window. This can sometimes
On the default VLAN clients can get IP addresses no problem and in seconds. But as soon as we try and work across vlans we are having an issue where it can take up to 15 minutes for a
Though primarily about how to diagnose problems once they start, the following two white papers might be useful in avoiding issues in the first place: ESX IP Storage Troubleshooting Best Practice: Packet
