AnyConnect and security updates, nothing specific...
Important notice
- This is an early-stage beta version for the MX 16 release. Due to this, we recommend taking additional caution before upgrading production appliances. Where applicable, MX 15 or MX 14 releases will provide a more stable upgrade alternative.
Legacy products notice
- When configured for this version, Z1, MX60, MX60W, MX80, and MX90 devices will run MX 14.55.
Bug fixes
- Updated the AnyConnect VPN service.
- Security updates
Known issues
- After making some configuration changes on MX84 appliances, a brief period of packet loss may occur. This will affect all MX84 appliances on all MX firmware versions
- Some stability-impacting issues present in MX 14 that affect a small population of MX67(C,W) and MX68(W,CW) appliances still exist.
- Some stability-impacting issues present in MX 14 that affect a small population of Z3(C) appliances still exist.
- Please note that until certification has been obtained, the Z3C will not be supported on Verizon's network.
- World-wide device SKUs of the MX67C, MX68CW, and Z3C units cannot be deployed in North America and North America device SKUs of the MX67C, MX68CW, and Z3C units cannot be deployed outside of North America.
- When deployed in warm spare / high availability (HA), MX67C and MX68CW do not support using their cellular connectivity to pass client traffic. In this deployment, the cellular connectivity can only be used for device monitoring or network troubleshooting. This is an expected limitation for these platforms.
- MX67C, MX68CW, and Z3C units must be connected to the Meraki Dashboard initially to retrieve an update to allow for proper use of the integrated cellular connectivity. This is most likely to be an issue when bringing the units online for the very first time.
- On the MX67(C,W) and MX68(W,CW) platforms, when the MX is providing PoE to a connected device, this information will not be reflected on the Meraki Dashboard.
- Due to MX 15 regressions, USB cellular connectivity may be less reliable on some modems
- Due to an MX 15 regression, the management port on MX84 appliances does not provide access to the local status page
- Client traffic will be dropped by MX65(W), MX67(C,W), and MX68(W,CW) appliances if 1) The client is connected to a LAN port with 802.1X authentication enabled and 2) The VLAN ID of the port is configured to 16, 32, 48, 64, 80, 96, 112, 128, 144, 160, 176, 192, 208, 224, or 240.
- Significant performance regressions for VPN traffic may be observed on MX84 and MX100 appliances
- Group policies do not correctly apply to client devices
- Z3(C) appliances that are upgraded to MX 16 versions cannot directly downgrade to MX 14 releases. They must first downgrade to an MX 15 release.
- MX IDS security alerts are not detected for AnyConnect VPN traffic
- BGP-learned routes may not be properly reflected in the Route Table page on the Meraki Dashboard, despite BGP and packet routing operating correctly.
- There is an increased risk of encountering device stability issues on all platforms and across all configurations.
