![]() Sending 5, 100-byte ICMP Echos to 12.1.1.1, timeout is 2 seconds: Success rate is 100 percent (5/5), round-trip min/avg/max = 12/18/24 ms SW1(config-if)#no switchport trunk encapsulation dot1q Looks like we have a lingering remnant from previous work… Let’s get rid of that and see what happens: SW1#conf tĮnter configuration commands, one per line. Let’s check the physical switch: SW1#sh run int fa0/1 That’s all fine, we have the correct ports in the correct vlan. Well let’s double check our configuration, starting with our virtual switch: We are getting double entries though, and a ping from R1 to R2 still does not work. Now things look a bit better: R1#sh cdp neigh | beg Device %Portfast has been configured on FastEthernet1/0/2 but will onlyīreakout(config-if)#switchport trunk encap dot1q Have effect when the interface is in a non-trunking mode.īreakout(config-if)#desc Down to SW1 f0/2 %Portfast has been configured on FastEthernet1/0/1 but will only Interface when portfast is enabled, can cause temporary bridging loops.

We know that the interfaces are up because they are in the MAC address table on the breakout switch. Sending 5, 100-byte ICMP Echos to 12.1.1.2, timeout is 2 seconds: SW1(config-if-range)#switchport access vlan 12 SW1(config-if-range)#switchport mode access The first (proper) task on the Narbik workbook is to put both R1 and R2 in VLAN 12 and make sure that they can ping each other. No problems there! But what we actually need is for them to be connected to SW1. S - Switch, H - Host, I - IGMP, r - Repeater, P - Phoneĭevice ID Local Intrfce Holdtme Capability Platform Port ID Total Mac Addresses for this criterion: 3Ĭapability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge So we have both lines up that connect us to the real network, let’s see if we can see them on the breakout switch: Breakout#sh mac-address-table int fa1/0/48 With that all done and the first couple of routers fired up we can check for basic connectivity: R1#sh int fa 0/0 | i line|addressįastEthernet0/0 is up, line protocol is up The ASA is just for fun, and I need a couple of crossover cables for the 3550s. The rack ears for the 3550 arrived a few moments ago and now the switch is sitting properly in the rack. ![]() I am also still waiting for the rack ears for the top 3550 to arrive. ![]() This also meant having to buy another switch, so there is a space to fill in between the 3560 and the cable management bit. But it also means that I need to use GNS3 and a breakout switch to connect to the real switches. I will still be able to find a use for the 1841s, but as far as the others go, they are just space fillers in the garage. I did realise though that now the v5 has replaced the v4 all my routers are redundant. I am using a 12u desktop rack which was a good price at just over £30 from .uk, you can get the same rack in the USA for just under $50. I have brought all my routers and switches home from work and now the routers are sitting in the garage and the switches are racked and ready. I am starting to get myself ready for the Narbik course in a few months time. ![]()
