想請教透過 Cisco route 指令查詢,某個高流量的IP?

sh ver

Cisco IOS XE Software, Version 16.09.02
...
cisco ISR4221/K9 (1RU) processor with 1784702K/6147K bytes of memory.
Processor board ID FGL22471419

自從換了 4200 之後,我以前查到指令皆沒?
請教? 該如何設?

網上提到使用 ip accounting 指令

A# conf t
Enter configuration commands, one per line. End with CNTL/Z.
A(config)#int g0/0/0
A(config-if)#ip ?
Interface IP configuration subcommands:
access-group Specify access control for packets
address Set the IP address of an interface
admission Apply Network Admission Control
auth-proxy Apply authenticaton proxy
authentication authentication subcommands

但我 route 則無此指令!

-- 在 cisco 1941 曾使用? ip cache flow 查看

!
ip dep
...
interface GigabitEthernet0/0
ip address 210.61.129.126 255.255.255.128
no ip redirects
no ip proxy-arp
ip flow ingress (ip route-cache flow)
ip flow egress (<-- 這行也要下)
ip route-cache cef (<-- 才能完整 disable no ip route-cache)
duplex auto
speed auto
...

A# sh ip cache g0/0 flow

但在新的 ISO XE 都沒提供?
懇請網友教導?

謝謝.
