Show commands allow you to display information. Table 2-14. Show Commands (1 of 4)
show arp
Minimum Access Level: Operator Command Mode: Standard
Displays the devices in the ARP table.
The general format of the show arp command is:
The first column displays the IP address. The second column displays the actual time left for the specific entry, or “STATIC” for configured static entries. The third column displays the MAC address for the ARP entry. The fourth column displays the ARP type (only ARPA is currently supported). The fifth column displays the Interface or sub-interface for the ARP table entry.
show bridge
Minimum Access Level: Operator Command Mode: Standard
Displays entries in the bridge forwarding database.
show configuration
Minimum Access Level: Operator Command Mode: Standard
Displays/outputs a sequence of commands in the form of ASCII strings that have the effect of setting all configurable parameters to the current values in memory. Passwords are write-only and not output. The text file can be used with a terminal emulation program. Refer to Configuring the Router Using Terminal Emulation in Chapter 1, Configuring the iMarc SLV Router.
The general format of the show config command is:
global commands ! interface n interface n commands.... ! interface n sub-interface n
interface n sub-interface n commands... !
interface n sub-interface n+1
interface n sub-interface n+1 commands... interface n+1
IP Address Timeout (min) MAC address Type Interface
x.x.x.x STATIC xx:xx:xx:xx:xx:xx ARPA
show configuration {saved | unsaved}
Minimum Access Level: Administrator Command Mode: All config modes
Displays/outputs a sequence of commands in the form of ASCII strings that have the effect of setting all configurable parameters to the current values, either saved in memory or entered during a current configuration session.
Passwords are write-only and not output. The text file can be used with a terminal emulation program. Refer to Configuring the Router Using Terminal Emulation in Chapter 1, Configuring the iMarc SLV Router. The general format of the show config command is the same as the previous command, show configuration, in Standard mode.
saved – Displays the command sequence for saving parameters currently saved in
memory.
unsaved – Displays the command sequence for saving parameters entered during the
current configuration session.
show frame-relay map
Minimum Access Level: Operator Command Mode: Standard
Displays the status of all frame relay DLCIs seen on the router’s frame relay interface. The general format of the show frame-relay map command is:
interface (interface-status): dlci dlci-number, dlci-status
Where the interface (or sub-interface) shall be displayed in the standard format shown in the Interface Commands. The interface-status is up or down. The dlci-number is in the range 16–1007. Frame relay map statements are only displayed for DLCIs configured on both the router and on the devices user interface. The dlci-status is active or inactive.
show interface [intf-type intf-num [.sub-intf-num]]
Minimum Access Level: Operator Command Mode: Standard
Shows the status of the named interface, sub-interface, or all interfaces and sub-interfaces on the device.
intf-type – The interface type. The following two types are supported:
Ethernet – IEEE 802.3 interface Serial – Serial interface
intf-num – The interface index number for the Ethernet and the Serial interfaces: 0. sub-intf-num – The sub-interface numbers are only supported on the Network interface (Serial 0). Sub-interface numbers supported: 0–4,294,967,295.
show ip dhcp binding [ ip-address]
Minimum Access Level: Operator Command Mode: Standard
Allows users to display address bindings associated with the DHCP server. If the IP address is not specified, all DHCP server bindings are displayed. If an IP address is specified, only the DHCP server binding for the specified client is displayed.
ip-address – Specifies the DHCP client’s IP address for the binding to be displayed. The general format of the show ip dhcp bindings command is as follows:
IP Address MAC address Lease Expires
x.x.x.x xx:xx:xx:xx:xx:xx ddd:hh:mm
The first column displays the IP addresses in use. The second column displays the MAC address bound to each IP address. The third column displays the remaining lease time in days, hours, and minutes or “Infinite”.
show ip nat translations
Minimum Access Level: Operator Command Mode: Standard
Shows the active Network Address Translation (NAT) translations. The general format of the show ip nat translations command is:
ProInside globalInside localOutside localOutside global udpx.x.x.x:portx.x.x.x:portx.x.x.x:port x.x.x.x:port
The first column, Pro, displays the Protocol of the port identifying the address. The second column displays the Inside global IP address for one or more inside local IP addresses to the outside world. The third column displays the Inside local IP address assigned to a host on the inside network.
The fourth column displays the Outside local IP address of an outside host as it appears to the inside network. The fifth column displays the Outside global IP address assigned to a host on the outside network by its owner. Whenever one of the IP addresses or the Protocol designation does not apply to a NAT table entry, “---” is displayed. A protocol port is appended to IP addresses when NAPT is specified for that NAT entry.
show ip route [ip-address]
Minimum Access Level: Operator Command Mode: Standard
This command shows the IP route table entry for the specified IP address. If no IP address is specified, the entire table is shown. When the Next Hop IP Address is 0.0.0.0, the host is directly reachable on the interface.
The general format of the show ip route command will be as follows: Dest. IP AddressDest. Subnet Mask Next Hop IP AddrInterface
x.x.x.x x.x.x.x x.x.x.x interface
x.x.x.x x.x.x.x x.x.x.x interface
ip-address – Specific IP address for route information display. show ip traffic
Minimum Access Level: Operator Command Mode: Standard
Displays the IP statistics for the device. Table 2-14. Show Commands (3 of 4)
show spanning-tree
Minimum Access Level: Operator Command Mode: Standard
Displays the devices spanning-tree topology. Table 2-14. Show Commands (4 of 4)
