Testing Connectivity; Pinging An Ip Address; Tracing A Route; Troubleshooting Network Connections - Brocade Communications Systems ICX 6650 Hardware Installation Manual

2. Gently insert the cable connector (a tab on each connector should face upward) into the transceiver connector until the tabs lock
into place.
3. Observe the link and active LEDs to determine if the network connections are functioning properly. For more information about
the LED indicators, refer to
Cleaning the fiber-optic connectors
To avoid problems with the connection between the fiber-optic transceiver (SFP, SFP+, or QSFP+) and the fiber cable connectors,
Brocade strongly recommends cleaning both connectors each time you disconnect and reconnect them. Dust can accumulate in the
connectors and cause problems, such as reducing the optic launch power.
To clean the fiber cable connectors, Brocade recommends using a fiber-optic reel-type cleaner. When not using an SFP connector, make
sure to keep the protective covering in place.

Testing connectivity

Test for connectivity by observing the LEDs related to network connection.

Pinging an IP address

To verify that a Brocade ICX 6650 can reach another device through the network, enter a command similar to the following at any level
of the CLI.
device# ping 192.168.0.0
Syntax: ping ip_addr [ source ip_addr ] [ count num ] [ timeout msec ] [ ttl num ] [ verify ] [ no-fragment ] [ quiet ] [ data 1-to-4 byte
hex#, e.g. abcdef00 ] [ numeric ] [ size byte ] [ brief [ max-print-per-sec num 0-2047 ] ]
NOTE
If you address the ping to the IP broadcast address, the device lists the first four
responses.
If a problem persists after taking these actions, contact Brocade Technical Support.

Tracing a route

To determine the path through which a Brocade device can reach another device, enter a command similar to the following at any level of
the CLI.
Brocade# traceroute 192.168.0.0
Syntax: traceroute host-ip-addr [ maxttl value ] [ minttl value ] [ numeric ] [ timeout value ] [ source-ip ipaddr ]
The CLI displays trace route information for each hop as soon as the information is received. Traceroute requests display all responses to
a given TTL. In addition, if there are multiple equal-cost routes to the destination, the Brocade device displays up to two responses by
default.

Troubleshooting network connections

• For the indicated port, verify that both ends of the cabling (at the device and the connected device) are snug.
