This document describes the new features, limitations, troubleshooting, besides providing recommended configurations, caveats, and information on how to obtain support and documentation.


Note
The documentation set for this product strives to use bias-free language. For purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Cisco ESR6300 Embedded Series Router

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 (NCP = No Cooling Plate)

  • ESR-6300-CON-K9: Embedded Router Board without a cooling plate (NCP = No Cooling Plate)

Both of the SKUs offer the following port and module interfaces:

  • Four GE LAN ports

  • Two combo GE WAN ports

  • One USB 3.0 port

  • One mSATA module interface

IPv6 Control Plane for DLEP

IOS-XE 17.13.1 supports DLEP control plane session support on an IPv6 network. When both the router and radio are running an IPv6 stack, the router can initiate DLEP session setup over IPv6. Both manual mode and auto discovery mode are supported. When the router is configured with an IPv6 address and transport layer port details of listening radio, the router initiates DLEP session setup in manual mode.

New Command Line Interface

You can choose auto discovery mode by using the following new CLI:

<no> ip dlep set peer-discovery-mode ipv6

When Auto discovery mode is set using the above command, the router starts sending peer discovery signals as in the following example: 

Destination IP6 address: FF02::1:7
Destination UDP Port   : 854
Source IPv6 address.    : Global IPv6 address configured on DLEP interface or sub-interface
Source UDP Port.         : 55555

Upon receipt of discovery signals the radio responds with offer signals that consist of IPv6 connection point TLV as defined in DLEP RFC 8175.

The router uses the received IPv6 address and transport port number to further establish a DLEP TCP session with the radio node. Once the TCP connection is established, rest of DLEP state machine is common between manual mode and IPv6 auto discovery mode.

When the router DLEP interface is configured with dual stack, DLEP auto discovery starts depending on the configured mode. By default, the router starts with IPv4 discovery mode.

Current IOS-XE implementation assumes the IPv6 DLEP offer signal consists of IPv6 connection point TLV or nothing. When the IPv6 connection point TLV is missing in the offer signal, the router picks radio IPv6 address and transport layer port number from foreign socket from which offer signal is received.

The IPv6 address offered by the radio can be link local address of radio interface or any configured global Ipv6 address. The router can establish DLEP session with either of them.


Note
Any IPv4 connection point TLV received in IPv6 offer signal is ignored by the router.

DLEP session mode on the router interface is independent of session mode configured on other interfaces. The router can simultaneously support any of following modes on different interfaces:

  • IPv4 manual configuration

  • IPv4 auto discovery

  • IPv6 manual configuration

  • IPv6 auto discovery

The following example shows adding a sample manual mode ipv6 control plane configuration:

ip dlep vtemplate 1 port 11813 tcp port 11913 client ipv6 193::104 port 913

Switching DLEP Session Mode on the Router Interface

The following are Guidelines/Limitations:

  • Changing the DLEP session mode due to a configuration change on the interface requires a virtual template reconfiguration on the interface to force the mode change.

  • Changing the IPv6 address on the router DLEP interface when there is active session is not recommended. Any such change needs to be followed by virtual template reconfiguration on the interface.

  • Ensure global IPv6 address is configured on the interface prior to enabling DLEP.

  • A valid virtual template and vmi interface mapped to the physical interface needs to be present.

  • Configuration for auto discovery needs to be in the following order:
    interface GigabitEthernet <x/x/x>
    ip dlep set peer-discovery-mode ipv6
    ip dlep vtemplate 1

  • The command ip dlep set peer-discovery-mode ipv6 gets removed when removing the dlep vtemplate configuration from the interface, for example, no ip dlep vtemplate 1 and has to be reconfigured to enable it again.

Auto Discovery Mode Fallback

The default DLEP session auto discovery mode is IPv4. There is no fallback from IPv4 to IPv6 or vice versa depending on failure of the current mode. Ensure both the router and radio are configured so that auto discovery mode is same.

Known Limitations

This release has the following limitations or deviations from expected behavior. These limitations are listed below by router type.

Smart Licensing

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).

Caveats

Caveats describe unexpected behavior in Cisco IOS XE releases. Caveats listed as open in a prior release are carried forward to the next release as either open or resolved.

The Cisco Bug Search Tool (BST) is a gateway to the Cisco bug-tracking system, which maintains a comprehensive list of defects and vulnerabilities in Cisco products and software. The BST provides you with detailed defect information about your products and software.
