Nudm Interface (HTTP2)
HTTP2 Server IP: local IP address, Nudm listening server IP.
HTTP2 Server Port: local port, Nudm listening server Port, default 2123.
HTTP2 Client IP: local IP address for connecting to other NF.
HTTP2 Client Port: local port for connecting to other NF.
Enabled UDR
local-udr-enabled: “1” means using local xml subscription files, “0” means using external UDR.
UDR HTTP2 Server IP:
If local-udr-enabled=”1”, this IP serves as the UDR-Manage interface.
If local-udr-enabled=”0”, this IP is the external UDR address.
UDR HTTP2 Server Port:
If local-udr-enabled=”1”, this port serves as the UDR-Manage interface.
If local-udr-enabled=”0”, this port is the external UDR server port.

NOTE: the case of external UDR is not used.
op (system op): default value is “12 34 56 78 90 12 34 56 12 34 56 78 90 12 34 56”.
amf (system amf): default value is “80 00”.
ue-size: number of ue profiles.
ue-supi: user SUPI.
ue-usim-key: UE KI, default value is “12 34 56 78 90 12 34 56 78 90 12 34 56 78 90 12”.
aka-method: ue authentication method, 1 for 5G AKA, and 2 for EAP AKA’.
aka-algorithm: 1 is Milenage, 2 is XOR. By default, it is Milenage.
opc (UE opc, optional): If configured, system op won’t apply to this UE.
udm-ue.xml（用户签约数据）
It stores mapping between imsi and other subscription data idices. subscription data are stored in separate files.
default-snssai-index-list：如果 UE 不请求指定 SNSSAI 的话，UDM 会根据该配置项去轮循分配，表示 UE 默认的切片分配列表，作用于 UE 没有指定切片。如果 udm-snssai.xml 中定义的 SNSSAI 不支持 UE 请求指定的 DNN 的话，UDM 就会拒绝掉。
snssai-index-list：如果 UE 请求了指定 SNSSAI 的话，那么该切片必须要在这个列表内，作用于 UE 指定的切片。

问题 1：启动顺序问题，重启 UDM 后需要分别再重启 AMF、SMF，查看日志确保互联成功。重启 UDM 后，最好也重启 AMF 来刷新一下从 UDM 获取到的信息。
问题 2：validateDnnAndSnssai 失败。
