DGS-3130 Layer 3 Stackable Managed Switch CLI Reference Guide Command Default Level Level: 12. Usage Guideline This command specifies an access list to restrict the access via ping. Example This example shows how a standard IP access list is created and is specified as the access list to restrict access via ping. Only the host 226.1.1.1 is allowed to ping the Switch. Switch# configure terminal Switch(config)# ip access-list ping-filter Switch(config-ip-acl)# permit 226.1.1.1 0.0.0.0 Switch(config-ip-acl)# exit Switch(config)# ping access-class ping-filter Switch(config)# 41-3 traceroute This command is used to display a hop-by-hop path from the Switch through an IP network to a specific destination host. traceroute {[ip] IP-ADDRESS | [ipv6] IPV6-ADDRESS | HOST-NAME} [length LENGTH] [probe NUMBER] [timeout SECONDS] [max-ttl TTL] [port DEST-PORT] Parameters ip IP-ADDRESS ipv6 IPV6-ADDRESS HOST-NAME probe NUMBER timeout SECONDS max-ttl TTL port DEST-PORT (Optional) Specifies to use the IPv4 address. Specifies the IPv4 address of the destination host. (Optional) Specifies to use the IPv6 address. Specifies the IPv6 address of the system to discover. Specifies the host name of the system to discover. (Optional) Specifies the number of datagrams to send. The allowed range is from 1 to 1000. (Optional) Specifies the response timeout value, in seconds. (Optional) Specifies the maximum TTL value for outgoing UDP datagrams. The maximum allowed range is from 1 to 255. (Optional) Specifies the base UDP destination port number used in outgoing datagrams. This value is incremented each time a datagram is sent. The allowed range for the destination port is from 1 to 65535. Use this option in the unlikely event that the destination host is listening to a port in the default trace-route port range. Default By default, three 40-byte UDP datagrams with an Initial TTL of 1 is sent. The maximum TTL value is 30. The timeout period is 5 seconds. The destination base UDP port number is 33434. The query number for each TTL is 3. 460
