How to start / stop / restart / reload iptables on CentOS 7 / RHEL 7 I found another intersting thing. This is related to iptables. In previous CentOS versions, we used to stop iptables service by using the command service iptables stop or /etc/init.d/iptables stop. On newly shined CentOS 7 / Red Hat 7, with systemctl command we can control the service status.

- The two zeroes before the ISP’s router address are shorthand for an IP address of 0.0.0.0 and a mask of 0.0.0.0. The above commands create a very basic firewall, however, using a sophisticated device such as a Cisco PIX or ASA security appliance to perform such basic firewall functions is overkill.

- 1 It tells you how the box is configured right now. 2  Also, show startup-config will tell you how the router will be configured after the next reboot. 3  show port: Similar to the show interface command on routers, this command gives you the status of ports on a switch.n most networks, the staple of information gathering has been the show commands. Here are my top ten commands to know and love: 1  show version: Start simple; this command gives uptime, info about your software and hardware and a few other details.

How Does the Passive Interface Feature Work in EIGRP? The passive interface Command. With EIGRP running on a network, the passive-interface command stops both outgoing and incoming routing updates, since the effect of the command causes the router to stop sending and receiving hello packets over an interface.he command enables the suppression of routing updates over some interfaces while it allows updates to be exchanged normally over other interfaces. With most routing protocols, the passive-interface command restricts outgoing advertisements only.

Configuring a Gateway of Last Resort Using IP Commands For instance, if the router is a host in the IP world, you can use this command to define a default gateway for it. You might also use this command when your low end Cisco router is in boot mode in order to TFTP a Cisco IOS® Software image to the router. In boot mode, the router does not have ip routing enabled.

Basic IOS Commands for Routers and Switches A couple of important commands you can use at the line configuration mode are the exec-timeout [minutes][seconds] and logging synchronous commands. The first one sets the timeout for the specific line and the second one stops annoying pop-up messages from disrupting whatever you are trying to type.

Configuring the Switch IP Address and Default Gateway • Reverse Address Resolution Protocol (RARP). The switch makes DHCP and RARP requests only if the sc0 interface IP address is set to 0.0.0.0 when the switch boots up. This address is the default for a new switch or a switch whose configuration file has been cleared using the clear config all command.

Using the ip classless command The ip classless command is enabled by default in Cisco IOS Software Release 11.3 and later. To disable this feature, use the no form of this command. When this feature is disabled any packets received that are destined for a subnet that falls within the subnetwork addressing scheme of the router will be discarded.

- Passive Interface (RIP,OSPF and EIGRP) explained with interview questions. by Shabeer ibm. Passive-interface command is used in all routing protocols to disable sending updates out from a specific interface.However the command behavior varies from o­ne protocol to another.n EIGRP the passive-interface command stops sending outgoing hello packets, hence the router can not form any neighbor relationship via the passive interface. This behavior stops both outgoing and incoming routing updates.
