What is the meaning of the tracert command output on an S series switch

9

For S series switches (except the S1700), the tracert command displays information about the path on which packets are sent from the source to the destination and checks network connectivity. When a fault occurs on the network, you can run this command to locate the fault. This command is used as follows:
[HUAWEI] tracert 192.168.10.10
traceroute to 192.168.10.10(192.168.10.10),max hops: 30 ,packet length: 40,press CTRL_C to break
1 10.16.16.12 23 ms 12 ms 6 ms
2 * * *
3 192.168.10.10 5 ms !<10> 5ms !<10> 6ms !<10>

The command output is described as follows:
1 indicates the first-hop gateway. The sequence number increases by each hop. By default, the maximum number of hops is 30.
10.16.16.12 indicates the gateway address of the first hop. The IPv4 address following the serial number of each hop is the gateway address of the hop.
23 ms 12 ms 6 ms indicates the time difference between the three sent UDP packets and the received ICMP Time Exceeded or ICMP Destination Unreachable packets.
* * * indicates that no ICMP Time Exceeded packet or ICMP Destination Unreachable packet is received on the second-hop device within a specified period.
! indicates an ICMP Destination Unreachable packet.
<10> indicates that the value of the Code field in the ICMP packet is 10, which means that the Destination host is administratively prohibited. There are no reachable routes between the destination host and the source address. This packet is sent by the default gateway of the destination host.
For the meanings of other values of the Type and Code fields in an ICMP packet, see Chapter 6 in TCP/IP Illustration Volume I.

What are the meanings of flags in the display fib command output for S series switches
Q: What are the meanings of flags in the display fib command output? A: The values of flags are as follows: B: indicates a blackhole route, that is, a route with the outbound interface being NULL0. D: indicates a route generated by a dynamic routing protocol such as IS-IS, OSPF, BGP, or RIP. G: indicates a gateway route, that is, a route destined for a gateway. H: indicates a host route. L: indicates a route generated by Address Resolution Protocol (ARP) or End System to Intermediate System (ESIS) routing exchange protocol, which is common in VLAN-ARP scenarios. S: indicates a static route, that is, a route configured using the ip route-static command or configured on the NMS. U: indicates that a route is reachable.

What is the meaning of bps in the command output
bps in the command output is the unit of a packet sending rate, which is also expressed in bit/s.

Meanings of the lease field in dhcp snooping command output on S series switch
For S series switches, the lease field in the outputs of DHCP snooping configuration indicates the lease of IP addresses configured on the DHCP server. The lease time varies depending on network access requirements. By default, the IP address lease is one day. - In locations where clients often move, for example, cafes, airports, and hotels, plan a short-term lease to ensure that IP addresses are released quickly after the clients go offline. - In locations where clients seldom move, for example, office areas of an enterprise, plan a long-term lease to prevent services from being affected by frequent address renewals. Different address pools on a DHCP server can be configured with different IP address leases, but the IP addresses in an address pool must be configured with the same lease. You can run the following commands to modify the lease time: - Run the dhcp server lease { day day [ hour hour [ minute minute ] ] | unlimited } command to set the lease for IP addresses in an interface address pool. For example, set the IP address lease of the address pool on VLANIF 100 to 2 days 2 hours and 30 minutes. [HUAWEI] dhcp enable [HUAWEI] interface vlanif 100 [HUAWEI-Vlanif100] ip address 10.10.10.10 24 [HUAWEI-Vlanif100] dhcp select interface [HUAWEI-Vlanif100] dhcp server lease day 2 hour 2 minute 30 - Run the lease { day day [ hour hour [ minute minute ] ] | unlimited } command to set the lease for IP addresses in a global IP address pool. For example, set the IP address lease of the global address pool global1 to 2 day 2 hours and 30 minutes. [HUAWEI] ip pool global1 [HUAWEI-ip-pool-global1] lease day 2 hour 2 minute 30

The tracert command output does not display the IP address of a PE on the public network on an S series switch
After you perform the following operations on S series switches (except the S1700), the tracert command output does not display the IP address of a PE on the public network: 1. Run the undo ttl propagate command in the system view of the PE to set the TTL propagate mode of MPLS packets to pipe. 2. Run the reset mpls ldp command in the user view to reset MPLS LDPs.
