Re: Cannot Ping the Router with cisco 3560 switch

here are some configuration if this helps you anyhow.


Steps in Catalyst Switch 3560:
Code:
Switch # config t 
Switch (config) # vlan 10 
Switch (config) # vlan 20 
Switch (config) # interface e0 / 1 
Switch (config-fi) # vlan-membership static 10 
Switch (config-if) # interface e0 / 2 
Switch (config-if) # vlan-membership static 10 
Switch (config-if) # interface e0 / 4 
Switch (config-if) # vlan-membership static 20 
Switch (config-if) # interface e0 / 5 
Switch (config-if) # vlan-membership static 20 
Switch (config-if) # interface fastethernet0/26 
Switch (config-if) # Trunk On 
Switch (config-if) # exit 
Switch (config) # ip default gateway 10.0.0.3 
Switch (config) # ip add 10.0.0.5 255.255.0.0

The steps in ICT Router:
Code:
ICT-Router (config) # interface f0 / 0 
ICT-Router (config-if) # description Connected to a Switch 
ICT-Router (config-if) # exit 
ICT-Router (config) # interface f0/0.1 
ICT-Router (config-subif) # ip address 10.0.0.3 255.255.0.0 
ICT-Router (config-subif) # encapsulation ISL 1 
ICT-Router (config-subif) # exit 
ICT-Router (config) # interface fastethernet0/0.10 
ICT-Router (config-subif) # encapsulation ISL 10 
ICT-Router (config-subif) # ip address 10.22.47.140 255.255.0.0 
ICT-Router (config-subif) # exit 
ICT-Router (config) # interface fastethernet0/0.20 
ICT-Router (config-subif) # encapsulation ISL 20 
ICT-Router (config-subif) # ip address 192.168.0.3 255.255.0.0

Re: Cannot Ping the Router with cisco 3560 switch

I want to ask some fundamental thing about routers and switches that I read in some tutorials. what is meant by core switches and core routers? what it is just the term alone?

Re: Cannot Ping the Router with cisco 3560 switch

Core Switch / Router is usually found on enterprise networks large providers. Structure / hierarchy of the network there are basically 3 things are there: Access, Distribution, Core. Access = Access to network / connect to the customer directly. Distribution = points / nodes where all the access network is connected. Core = points / nodes connected to the distribution. In the Core Switch / Router no direct connection to the network Access.

Re: Cannot Ping the Router with cisco 3560 switch

Intervlan routing is one such example in this paper, occurs in the router ICT. The point inter-VLAN can not communicate (OSI layer 2), theif you want to be able to communicate between vlan (intervlan), then it should go up to layer 3 (Network Layer / IP). Intervlan routing can also be done in Catalyst Multilayer switches (3550 series and above) by making the SVI (Switch Virtual Interface). BGP Quote shelled could complete Chapter 2, that should provide a specific question. Tool for monitoring until the application layer can with wireshark. You can see the IP, TCP / UDP, application until the message is in it. Install this tool on your PC and connect to the switch / hub in your office LAN Center. Then you will be able to monitor all activity including those in the client2 office.

Re: Cannot Ping the Router with cisco 3560 switch

Due to a bug in the software of the firewall service module (FWSM), a series of specially crafted ICMP packets, Cisco routers and switches are standstill.

Re: Cannot Ping the Router with cisco 3560 switch

All FWSM software versions 2.x, 3.x and 4.x fix without special vulnerable. As Cisco points out in a security advisory, the execution result of ICMP packets to a processor that occupies all available execution threads. This means that the system does not forward packets. In addition, it also FSWM itself is not achievable over the network, a fully equipped fail-over could also fail.

Re: Cannot Ping the Router with cisco 3560 switch

The command show np 2 stats can tell you whether this problem has already occurred. The system this case provides, the message "ERROR: request for FP Stats failed np_logger_query". Workarounds, that no manufacturer, that does provide updated versions of the FWSM software, which will no longer occur the problem.

Re: Cannot Ping the Router with cisco 3560 switch

Your Cisco 3560 switches do not support NAT, so if you want a solution-vlan, vlan can connect to the internet / speedy you can change its topology by replacing the wireless modem with a Cisco router that has an ADSL port and a port FastEthernet. FastEthernet is connected to cat3560 configured as a VLAN trunk. Connect the ethernet port of your wireless modem to the Catalyst 3560 and Catalyst 3560 to Configure vlan on. Thereby you have internet access with a cable which is distributed from the Catalyst 3560 and the wireless is connected to 3560.

Re: Cannot Ping the Router with cisco 3560 switch

The key was in the router connected to ADSL / Internet. On this router you must create a sub-interface for vlan masing2, making masing2 DHCP for VLAN, and create a NAT / PAT with access list (ACL) for each VLAN subnet. So with many VLAN has an IP private masing2 different, client2 from masing2 VLAN TSB can still connect to the Internet.
