The ESR6300 is a small form factor embedded router module with a board size of 3.0 in. x 3.775 in. (76.2 mm x 95.885 mm).
The more compact design simplifies integration and offers system integrators the ability to use the Cisco ESR6300 in a wide variety of embedded applications. The ESR module is available with a Cisco-designed cooling plate customized to the ESR, as well as without the cooling plate for system integrators who want to design their own custom thermal solution.
There are two ESR6300 SKUs:
-
ESR-6300-NCP-K9: Embedded Router Board without a cooling plate
-
ESR-6300-CON-K9: Embedded Router Board with a cooling plate
Both SKUs offer the following port and module interfaces:
-
Four GE LAN ports
-
Two combo GE WAN ports
-
One USB 3.0 port

Known Limitations
Smart Licensing Using Policy
Starting with Cisco IOS XE 17.6.1, with the introduction of Smart Licensing Using Policy, even if you configure a hostname for a product instance or device, only the Unique Device Identifier (UDI) is displayed. This change in the display can be observed in all licensing utilities and user interfaces where the hostname was displayed in earlier releases. It does not affect any licensing functionality. There is no workaround for this limitation.
The licensing utilities and user interfaces that are affected by this limitation include only the following: Cisco Smart Software Manager (CSSM), Cisco Smart License Utility (CSLU), and Smart Software Manager On-Prem (SSM On-Prem).
IOx on the ESR6300
![]() Note |
IOx development is not supported on the ESR6300. While this is platform independent code, it is unsupported and untested on this device. |
Expansion Module on the IR1101
The expansion module IR1101 does not support more than 1500 MTU size on LAN interfaces. See this Caveat for details.
Standalone MAC Authentication Bypass (MAB) Limitation
Standalone MAC Authentication Bypass (MAB) is an authentication method that grants network access to specific MAC addresses regardless of 802.1X capability or credentials. The IR1100 crashes with concurrent IPSec traffic and macsec traffic (device to client).
Refer to the following table for details:
Details |
Release Affected |
Release Fixed |
||
---|---|---|---|---|
MAB/Dot1x may not work if the global type-6 encryption setting is enabled. If users still want to use MAB/Dot1x, they should disable the type-6 encryption and enable type-7 encryption. |
17.4.X 17.5.X 17.6.1 17.6.2 17.7.1 |
17.3.5 Fixed in these future releases: 17.6.3 17.7.2 17.8.1 and later. |
||
dACL and device-tracking features are not supported on the IR1101 due to a hardware limitation. dACL is supported on the IR1800 series. Therefore, features such as MAB and Dot1x should not be used with the optional dACL/device-tracking enabled. |
|
Hardware limitation, no software fix available. |
Caveats
