A better way to monitor the end-user experience

The concept of user performance management (UPM) is easy to understand but very difficult to implement. The Holy Grail of UPM would be a single, unified dashboard where IT operations would be able to “see” the status of every user. If a website were taking too long to load or an application were performing poorly, the operations staff could click on that user and immediately see where the problem is. One challenge for IT departments is that today’s user isn’t always a person. Thanks to the rise in the number of Internet of Things (IoT) devices, “headless” clients that provide critical services to users now pump data through the network. For example, medical devices deliver time-critical information that can be the difference between life and death. Getting a grip on how these headless devices are performing on the network has become a daunting task for IT staff. To read this article in full or to leave a comment, please click here

MC-LAG lab – advanced IRB functionality

For simplified Layer 3 gateway services, where Layer 3 routing protocols are not run on the MC-LAG peers, you simply configure the same Layer 3 gateway IP address on both MC-LAG peers and enable IRB MAC address synchronization. This IP address is used as the default gateway for the MC-LAG servers or hosts.
For more advanced Layer 3 gateway services, where Layer 3 routing protocols and Layer 3 multicast operations are required on the MC-LAG peers, you configure unique IRB interface addresses on each MC-LAG peer and then configured the virtual router redundancy protocol (VRRP) between the peers in an active/standby role.
To help with some forwarding operations, the IRB MAC address of each peer is replicated on the other peer and is installed as a MAC address with the forwarding next hop of the ICL-PL. This is achieved by configuring a static ARP entry for the remote peer.

IRB interfaces configurations:

vQFX1:
irb {
unit 100 {
family inet {
address 172.16.0.1/24 {
arp 172.16.0.2 l2-interface xe-0/ Continue reading
