S12500G-AF交换机新增下发track nqa配置时提示tcam资源不足

某客户做割接，新增跨vpn静态路由，还有部分跨vpn路由做了track联动，发现S12500G-AF交换机下发track nqa配置时，提示资源不足，不足的资源是tcam

%Jun 17 20:44:27:672 2026 N-Core2 SHELL/6/SHELL_CMD_EXECUTESUCCESS: -Line=vty0-User=adminjyw-IPAddr=10.99.131.4; Command vpn-instance N-LT in view nqa-n_ywlt-icmp_10.100.96.1-icmp-echo succeed to be executed. Result=Success.

%Jun 17 20:44:27:679 2026 N-Core2 DEV/2/BOARD_ALARM_OCCUR: Board alarm occurred. (PhysicalIndex=67, PhysicalName=Board 2, RelativeResource=(chiptype:tcam resource,slot:2,chipid:1), ErrorCode=425027, Reason=Insufficient entry resources on TCAM.)

TCAM是qacl硬件资源，通过命令检查底层资源下发情况，截取slot2 chip1 qacl情况检查看，还有剩余空间，iacl 6 7 还没用

S12500G-AF  R8056P10版本，首次配置静态路由跨VPN不指定下一跳地址命令时会报TCAM资源不足，不影响功能，R86XX已经优化过。

%Jun 17 20:44:27:672 2026 N-Core2 SHELL/6/SHELL_CMD_EXECUTESUCCESS: -Line=vty0-User=adminjyw-IPAddr=10.99.131.4; Command vpn-instance N-LT in view nqa-n_ywlt-icmp_10.100.96.1-icmp-echo succeed to be executed. Result=Success.

如果现场不涉及静态路由跨VPN成环的错误配置情况下（例如路由从vpn1 到vpn2，vpn2 又指到vpn1），不会有问题。
