While loading MIB file, saw error : "DESCRIPTION" is missing for "mib-jnx-chas-defines.txt"
Product-Group=evo
Issue: Error in loading MIB file 'jnx-chas-defines.mib'. Cause: The order of REVISION-DESCRIPTION statements in header section of a MIB file is REVISION statement followed by DESCRIPTION. But there were some change in jnx-chas-defines.mib which added one extra 'REVISION' statement at the end and this caused MIB file compilation error. Work-Around: If the above issue is seen while loading jnx-chas-defines.mib file which is part of junos-mibs*.tgz package, then add a 'DESCRIPTION' statement at the end of this MIB file header to avoid this error.

Unified led scheme for QFX5220/QFX5130
Product-Group=evo
Port LED behavior in QFX5220/QFX5130 is changed to unified led scheme. One caveat is that there is no red led color support and hence for xcvr fault port LED will be OFF and when beacon is enabled in fault state, port LED is Green blinking. There are two caveats in led behavior, 1. When interface is disabled, led is off instead of amber lit. 2. When interface is channelized and partially up, earlier LED was blinking green. Now it was steady amber.

PTX10003 load balance v4_dscp and v6_dscp is enabled by default
Product-Group=evo
PTX10003 load balance v4_dscp and v6_dscp is enabled by default. This default behavior may cause traffic loss / out of order / retransmission to some application. To turn it off, please contact JTAC to get PFE commands to disable the hashing as there's no configuration knob to change this behavior. With the fix of this PR: 1. v4_dscp and v4_dp is set default as 0(disabled), config "hash-key family inet layer-4 type-of-service" will enable v4_dscp and v4_dp: set forwarding-options hash-key family inet layer-4 type-of-service 2. v6_dscp and v6_dp is set default as 0(disable), config "hash-key family inet6 layer-3 traffic-class" will enable v6_dscp and v6_dp set forwarding-options hash-key family inet6 layer-3 traffic-class
