The application calls NANO_XRCE_Client_disconnect() to perform a “cleanĭisconnection” from the Agent. The flag is lifted upon reception of a connection reply from the Agent, and it The client’s stores the “connection status” in an internal flag, which can beĬhecked using macro NANO_XRCE_Client_connected(). */ #define TRANSPORT_BUFFER_SIZE \ (NANO_OSAPI_Memory_align_size_up( \ TRANSPORT_MTU, sizeof(NANO_MessageBufferData)) / \ sizeof(NANO_MessageBufferData)) int main ( void ) Type NANO_MessageBufferData will always be defined to be at least 32-bit, and it can be used to guarantee this alignment.

If the client key is omitted, the XRCE Agent must be able to correlate the client's transport with the client's session (e.g. Depending on the selected session id, the exchanged XRCE messages will include the client's key in each message's header (if session id 0x80). #include "nano/nano_client.h" /* Clients can select any arbitrary, non-zero, 32-bit key */ #define CLIENT_KEY 0xABCDABCD /* Client's can select any non-zero session id, with the exception of values 0x01 and 0x80, which are reserved by the protocol. The following snippet shows how to initialize a NANO_XRCE_Client using the Transport implementations should also not perform any dynamic memory allocation,Īnd they will typically require applications to pass in a buffer for storing Which extends the base structure with additonal, transport-specific parameters. These include theĪgent’s locator and the MTU that should be enforced on the transport link.Įach transport implementation will typically define their own properties type, NANO_XRCE_ClientTransportProperties data structure.

Otherwise, large packets cannot be fragmented and service failures may occur. If the CRS1 and Huawei devices are interconnected through Ethernet interfaces in an MPLS VPN, the Ethernet interface MTU on the CRS1 must be greater than or equal to 1522. For example, if the MTU on Ethernet interfaces of the CRS1 is changed to 1518, then the MTU on Huawei devices needs to be changed to 1504 accordingly.Ģ. Otherwise, the ISIS neighbors will never be Up. Any change to the MTUs should be based on 15. The default MTU 1514 on Ethernet interfaces of the CRS1 corresponds to the MTU 1500 on Ethernet interfaces of Huawei devices. The IS-IS protocol is run on the Ethernet interface between the CRS1 and a Huawei router and Small-hello is not configured, the interface sends a Hello packet according to the MTU. The default MTU on the Ethernet interfaces of Huawei routers is 1500 bytes, which include only the packet payload.ġ. The default MTU on all Ethernet interfaces of the CRS1 is 1514 bytes, which include an Ethernet frame header and packet payload. The default MTU on all Ethernet interfaces of the routers (including 120xx, 100xx, 76xx, and 65xx) of the company is 1500 bytes, which include only the payload of packets. Special attention should be paid to the change of the default Ethernet interface MTU. The software system and default configurations of the CRS1 are greatly different from those of the legacy routers such as 120xx, 100xx, 76xx, and 65xx. The CRS1 is a TB router launched by Manufacturer C in 2007.
