12508X tracert超时，启用ip unreachables和ttl-expires无效

这两个命令应当允许设备在ICMP超时和不可达情况下返回相应报文，但在实际测试中，仍然出现多个跳数无响应的情况，尤其是在中间几跳持续超时，只有起始和终点设备响应正常，目前排查了ACL、安全策略等常规原因，均未发现异常，设备CPU资源充足，也未开启攻击防护类的丢弃策略，想请教下在这种配置已确认的前提下，还有哪些可能导致tracert中间跳数超时？或者是否tracert在这类高性能设备上存在特殊处理逻辑？weibo.com/ttarticle/p/show?id=2309405164026140164166weibo.com/ttarticle/p/show?id=2309405164026484359194weibo.com/ttarticle/p/show?id=2309405164028346368091weibo.com/ttarticle/p/show?id=2309405164027155447937weibo.com/ttarticle/p/show?id=2309405164028233384268weibo.com/ttarticle/p/show?id=2309405164027327414404weibo.com/ttarticle/p/show?id=2309405164026928955628weibo.com/ttarticle/p/show?id=2309405164027843313684weibo.com/ttarticle/p/show?id=2309405164027449049102weibo.com/ttarticle/p/show?id=2309405164027784593654weibo.com/ttarticle/p/show?id=2309405164025905545466weibo.com/ttarticle/p/show?id=2309405164027952365666weibo.com/ttarticle/p/show?id=2309405164027730067487weibo.com/ttarticle/p/show?id=2309405164028124332111weibo.com/ttarticle/p/show?id=2309405164028065611934weibo.com/ttarticle/p/show?id=2309405164026425638941weibo.com/ttarticle/p/show?id=2309405164026496942236weibo.com/ttarticle/p/show?id=2309405164027897577489weibo.com/ttarticle/p/show?id=2309405164026987413511weibo.com/ttarticle/p/show?id=2309405164025813008428weibo.com/ttarticle/p/show?id=2309405164026274644060weibo.com/ttarticle/p/show?id=2309405164026891206720weibo.com/ttarticle/p/show?id=2309405164028178858296weibo.com/ttarticle/p/show?id=2309405164025846825234weibo.com/ttarticle/p/show?id=2309405164026945732748weibo.com/ttarticle/p/show?id=2309405164026366656569weibo.com/ttarticle/p/show?id=2309405164027558101035weibo.com/ttarticle/p/show?id=2309405164028573122764weibo.com/ttarticle/p/show?id=2309405164028518596645weibo.com/ttarticle/p/show?id=2309405164027113504868weibo.com/ttarticle/p/show?id=2309405164028405088267weibo.com/ttarticle/p/show?id=2309405164027558101388weibo.com/ttarticle/p/show?id=2309405164026647937129weibo.com/ttarticle/p/show?id=2309405164026761183402weibo.com/ttarticle/p/show?id=2309405164026048151622weibo.com/ttarticle/p/show?id=2309405164026874429616weibo.com/ttarticle/p/show?id=2309405164027281276946weibo.com/ttarticle/p/show?id=2309405164028291842053weibo.com/ttarticle/p/show?id=2309405164028291842069weibo.com/ttarticle/p/show?id=2309405164026555662374weibo.com/ttarticle/p/show?id=2309405164027952365656weibo.com/ttarticle/p/show?id=2309405164028065349697weibo.com/ttarticle/p/show?id=2309405164027440660780weibo.com/ttarticle/p/show?id=2309405164025871990791weibo.com/ttarticle/p/show?id=2309405164027499380769weibo.com/ttarticle/p/show?id=2309405164026220118156weibo.com/ttarticle/p/show?id=2309405164027671347267weibo.com/ttarticle/p/show?id=2309405164027000258946weibo.com/ttarticle/p/show?id=2309405164026312130565weibo.com/ttarticle/p/show?id=2309405164027843051532weibo.com/ttarticle/p/show?id=2309405164026593411322weibo.com/ttarticle/p/show?id=2309405164027214168135weibo.com/ttarticle/p/show?id=2309405164028405350436weibo.com/ttarticle/p/show?id=2309405164028459876534weibo.com/ttarticle/p/show?id=2309405164025968459824weibo.com/ttarticle/p/show?id=2309405164026664714512weibo.com/ttarticle/p/show?id=2309405164026610188366weibo.com/ttarticle/p/show?id=2309405164027503575168weibo.com/ttarticle/p/show?id=2309405164028346630263weibo.com/ttarticle/p/show?id=2309405164027335802961weibo.com/ttarticle/p/show?id=2309405164028459614253weibo.com/ttarticle/p/show?id=2309405164028011085830weibo.com/ttarticle/p/show?id=2309405164026081443980weibo.com/ttarticle/p/show?id=2309405164027390329172weibo.com/ttarticle/p/show?id=2309405164027675279375weibo.com/ttarticle/p/show?id=2309405164028572860447weibo.com/ttarticle/p/show?id=2309405164025930711153weibo.com/ttarticle/p/show?id=2309405164028233384298weibo.com/ttarticle/p/show?id=2309405164027058978875weibo.com/ttarticle/p/show?id=2309405164026437959741weibo.com/ttarticle/p/show?id=2309405164026538885186weibo.com/ttarticle/p/show?id=2309405164025989431580weibo.com/ttarticle/p/show?id=2309405164027612627208weibo.com/ttarticle/p/show?id=2309405164027616821299weibo.com/ttarticle/p/show?id=2309405164026328907851weibo.com/ttarticle/p/show?id=2309405164026249216107weibo.com/ttarticle/p/show?id=2309405164026836418570weibo.com/ttarticle/p/show?id=2309405164028124069940weibo.com/ttarticle/p/show?id=2309405164027042201938weibo.com/ttarticle/p/show?id=2309405164028518596614weibo.com/ttarticle/p/show?id=2309405164026106609670weibo.com/ttarticle/p/show?id=2309405164026383433819weibo.com/ttarticle/p/show?id=2309405164026706657454weibo.com/ttarticle/p/show?id=2309405164026723172366weibo.com/ttarticle/p/show?id=2309405164027784593624weibo.com/ttarticle/p/show?id=2309405164026027180144weibo.com/ttarticle/p/show?id=2309405164026194952388weibo.com/ttarticle/p/show?id=2309405164028178858101weibo.com/ttarticle/p/show?id=2309405164027272626224weibo.com/ttarticle/p/show?id=2309405164027386134694weibo.com/ttarticle/p/show?id=2309405164027226488838weibo.com/ttarticle/p/show?id=2309405164026819903594weibo.com/ttart
