A Network Operator is investigating a report of intermittent connectivity between a user in the Sales VLAN (VLAN 10, subnet 192.168.10.0/24) and a server in the Finance VLAN (VLAN 20, subnet 192.168.20.0/24). The operator suspects a routing issue on the core switch that handles inter-VLAN routing.
The operator logs into the core switch and runs `show ip route`.
show ip route
Codes: C - Connected, S - Static, R - RIP, O - OSPF, B - BGP > - Selected route, * - FIB route S > 0.0.0.0/0 [1/0] via 172.16.1.1, vlan1 C > 172.16.1.0/30 is directly connected, vlan1 C > 192.168.10.0/24 is directly connected, vlan10 C > 192.168.20.0/24 is directly connected, vlan20 O > 192.168.30.0/24 [110/2] via 172.16.1.1, vlan1 The routing table appears correct. To investigate the *intermittent* nature of the problem, the operator needs to see the real-time, hop-by-hop path the traffic is taking between the user and the server. Which command should the operator use from the core switch's CLI to trace this path?
A solutions architect is designing a resilient routing solution for a campus network. A critical requirement is that if a primary link to the internet fails, traffic must automatically re-route through a secondary link with minimal packet loss. The primary link has a bandwidth of 1Gbps and the secondary link is 100Mbps.
The administrator is considering using static routes.
Review the following proposed configuration on the core switch:
ip route 0.0.0.0/0 10.100.1.1
ip route 0.0.0.0/0 10.200.1.1
How can the administrator ensure the 1Gbps link (via 10.100.1.1) is the primary path and the
100Mbps link (via 10.200.1.1) is only used for failover?
A Solutions Architect is investigating a complex, intermittent issue in a multi-tier campus network.
Users are reporting that access to a critical internal application server (10.100.1.50) is periodically slow or times out. The network consists of multiple AOS-CX switches. The architect suspects a routing problem or a silent packet drop at one of the intermediate Layer 3 hops. The goal is to non-disruptively trace the path and identify the point of failure.
Which general troubleshooting tool should the architect use from the user's gateway switch to identify every Layer 3 hop on the path to the application server and measure the latency to each hop?
A network technician is troubleshooting a user's complaint of being unable to reach a server. The technician uses the `ping` command from the user's default gateway (an AOS-CX switch) to the server's IP address (172.16.30.10) and receives a "Destination Host Unreachable" message. The technician then displays the switch's IP route table.
Review the routing table output:
show ip route
Codes: C - Connected, S - Static, R - RIP, O - OSPF, B - BGP > - Selected route, * - FIB route S > 0.0.0.0/0 [1/0] via 10.1.254.1, vlan1 C > 10.1.0.0/16 is directly connected, vlan1 C > 192.168.1.0/24 is directly connected, vlan100 O > 192.168.50.0/24 [110/1] via 10.1.1.2, vlan1 Based on the routing table, what is the most likely cause of the "Destination Host Unreachable" error?
