If you are only talking about traditional Virtual Chassis (VC) (ring topology) then yes you can mix dedicated VCP and uplink ports converted into VCP (10G/1G). Please refer to the EX4200 section of the documentation. If you are looking at using Virtual Chassis Fabric (VCF) (Clos topology), it should still work, but I didn't confirm this. You'd probably run ...

EX4300s have four QSFP+ ports (rear panel) which may be used for stacking or as 40GbE. They also don't require an uplink module (EX-UM-xxx) and therefore have four SFP+ 1/10G ports (front panel) in the base model. The newer software on EX4300 makes one shocking choice you need to be aware of. STP may be disabled in a factory-default configuration. That ...

If you're looking at purchasing new hardware, EX4300s are generally recommended. It's not that there's anything wrong with the EX4200, it's simply that the EX4300 is the next generation with new features, longer term support, etc. Technically speaking, without getting into all of the finite variations on each model within both platforms, the main ...

After going over the existing documentation it appears that it is supported but not implemented, allow me to expand. The TRAP jnxSecAccessIfMacLimitExceeded falls under Port Security Features, hence the mac-limit would be under the secure-access-port stanza, and as per documentation, these actions differ from the interface-mac-limit packet-action; they don't ...

I have found answer from the Juniper documentation as below:- The graceful Routing Engine switchover (GRES) feature in Junos OS and Junos OS Evolved enables a router with redundant Routing Engines to continue forwarding packets, even if one Routing Engine fails. GRES preserves interface and kernel information. Traffic is not interrupted. However, GRES does ...

LAG aggregates multiple physical links into a single, logical one. It can achieve link-level redundancy and a (possibly limited) increase in link bandwidth. With very few exceptions, LAG doesn't load balance traffic across the physical links. Instead traffic is distributed using a static scheme. Depending on your hardware and its configuration, that ...
