I have a cisco ASA 5505 and i try to configure its interfaces but when i enter the commande to set the ip it marks me ' Invalid input detected at '^' marker.' #conf t (config)# interface ethernet0/0 (config-if)# ip 192.168.2.100 255.255.255.0 Invalid input detected at '^' marker. Q: What is the problem with an interface if you type the router show interface serial 0 command and receive the following message? Serial0 is administratively down, line protocol is down a. A serial interface can come in a variety of different physical forms, such as V.35, X.21, and EIA-530. The choice of physical media often depends on geographical location; V.35 is the most common choice in the United States and Europe, and X.21 is more common in Japan.

Description
The OM-ES-020 ethernet to serial device server is ideal for industrial applications. Data transfer rates up to 1,000,000 baud, coupled with 1Mbit/s line drivers deliver uncompromising performance. The OM-ES-020 range provides simple instant networked serial ports. A web interface allows secure configuration and control of the serial ports over a local network or the internet using any browser.For Windows® our 32- and 64-bit driver gives you local COM ports, retaining existing software applications and allowing you to connect across your network to remote devices just as if they were attached locally. You can access the device via TCP/IP sockets from any networked device like an Android tablet, PC or phone. Serial port tunneling (individually configurable) allows serial cable replacement over any distance, no software required. On Windows OS TCP/IP sockets are handled by the Winsock API, this will differ on other OSs. The OM-ES-020 can be wired into existing power and network infrastructure or it can be used with a separate power supply.
Windows Users Our software drivers give you local COM ports, allowing you to retain your existing software applications and connect to your devices over the network. COM Port can be assigned from COM1 to COM255 and the OM-ES-020 ethernet to serial device remembers your COM Port assignment on reboots.
Web Interface Users (Linux/Apple OS/Android)
Alternatively access the device via TCP/IP socket from any networked device. Configure options via web interface.

This post explains the interface numbering scheme used in Cisco 1800, Cisco 2800 and Cisco 3800 Series Routers. It also includes line numbering associated with async interfaces.
Existing router platforms (earlier than Cisco 1800, Cisco 2800, and Cisco 3800) contain a limitation. In some situations, such as when you insert WIC(s) out of order, the configuration of one WIC interface can be lost or applied to another WIC interface.
Example: Assume that you have a serial WIC-2T in WIC slot 1 and WIC slot 0 is empty. The interfaces are named serial 0/0 and serial 0/1. If you insert another WIC-2T into slot 0, the new WIC interfaces are named serial 0/0 and serial 0/1. The old WIC interfaces become serial 0/2 and serial 0/3. Therefore, the old WIC interface configuration moves to the new WIC interfaces.
Refer to How Async Lines are Numbered in Cisco 3600 Series Routers for more information.
In order to overcome this limitation, Cisco 1800, Cisco 2800, and Cisco3800 series platforms now have a three-tiered interface numbering format (slot/subslot/port) for interfaces on WIC slots only.
Note: The slot information for the Cisco 3800 series is the same as the 2800/1800 interface and line numbering. See New Interface and Line Number Conventions for information on interface and line numbering.
New Interface and Line Number Conventions
This section describes the new conventions for interface and line numbering.
- The interface numbering scheme is the same for async interfaces and non-async interfaces. To configure the line associated with an async interface, use the interface number to specify the async line.For example, line 0/0/0 specifies the line associated with interface serial 0/0/0 on a WIC-2A/S in slot 0. Similarly, line 0/1/1 specifies the line associated with interface async 0/1/1 on a WIC-2AM in slot 1.Note: This document uses the following words interchangeably:
- Network-module-slot and slot.
- Interface-card-slot and subslot.
- Ports on network modules are numbered like this:interface-number = network-module-slot/portORinterface-number = slot/port
- Ports on interface cards (such as WICs, VWICs and HWICs) installed directly in chassis slots is given here:interface-number = 0/interface-card-slot/portORinterface-number = 0/subslot/port
- This numbering convention is used for ports on interface cards that are installed in network module slots:interface-number = network-module-slot/interface-card-slot/portORinterface-number = slot/subslot/portNote: The slot/subslot/port format only applies to WIC interfaces. Interfaces that are native to the network modules still use only the slot/port format. That is:
- <interface-name> slot/port is used whenever the interfaces are native on the network module.
- <interface-name> slot/subslot/port is used whenever the interfaces are on the WIC slot of a network module (NM).
- Here is an example for numbering when the motherboard slot number is always 0. The native interfaces on the motherboard are numbered like this:
- Fa0/0, Fa0/1 on Cisco 2811.
- Gi0/0, and Gi0/1 on Cisco 2821 and Cisco 2851.
The Motherboard WIC slots are numbered from 0 to 3. The number increments from right to left, and from bottom to top. - Slot numbers for other slots increase from bottom to top, then right to left. Subslot numbers and port numbers within a slot also increase from bottom to top, then right to left.
Examples
Interfaces native to an extension network module (ENM):
If the ENM carries WIC cards, the WIC slot numbers start from 0:
The extension voice module (EVM) slot analog interfaces are numbered from voice-port 2/0/0 to voice-port 2/0/23, following the NM-HDA convention.
