SIMULATION -

A network technician replaced an access layer switch and needs to reconfigure it to allow the connected devices to connect to the correct networks.


INSTRUCTIONS -

Click on the appropriate port(s) on Switch 1 and Switch 3 to verify or reconfigure the correct settings:
Ensure each device accesses only its correctly associated network.
Disable all unused switchports.
Require fault-tolerant connections between the switches.
Only make necessary changes to complete the above requirements.

Port enabled = connected devices Port disabled = no devices LACP enabled = if connected from switch to switch untagged VLAN = devices connected (servers, pc, printer...) tagged VLAN = if connected from switch to switch Should be pretty straightforward with that info.

After reviewing some outside notes and doing this on paper, I think the answer is this below. Correct me if anything may be wrong though: SWITCH 1: - The only thing that would need to be fixed here is to set all the Speed and Duplex values to auto. - All LACP, tagging, and VLAN assignments look to be correct. SWITCH 3: - For all ports, set Speed and Duplex to auto (although I guess disabled ones don't matter as much). - For all ports, remove from VLAN 1 (although, again, disabled ports might not matter as much). - Port 1 and Port 2: * Enable port * Enable LACP * Add following VLANS as TAGGED: 60, 90, 120, 220 - Port 3: * Disable port - Port 4: * Add to VLAN 220 TAGGED * Add to VLAN 120 untagged - Port 5: * Disable port - Port 6: * Add to VLAN 120 untagged - Port 7: * Add to VLAN 60 untagged - Port 8: * Add to VLAN 90 untagged

One half says to leave speeds at 1000, other side says to change to Auto. Any tie breakers here?

The instructions say specifically "Only make necessary changes to complete the above requirements" so I would just leave them as is. Comptia wording is probably the key here, safer to do exactly what it says than to touch anything extra

Oh I screwed up. Should just be replying to myself, instead of posting new. OK, I'll redo. Sorry guys.

For VLAN tagging, looks like on access-distribution trunk links, they only want VLANs that the access switches are using. Dist-core trunk links will need to carry all VLANs. You only tag VLANs on trunk links. Never on the ports endpoints are plugged into.

So basically, you leave Switch2 P3,4,5,7,8 and Switch3 P4,6,7,8 as untagged correct?

LACP should be enabled on all the trunk ports: Core switchports 1, 2; Switch 1 ports 1, 2, 5, 6, 7, 8; Switch 2 ports 1, 2; Switch 3 ports 1, 2

Looks like Switch 1 is a distribution layer switch with two servers hanging off of it Switch 2 and 3 are access layer switches.

Unless scenario indicates a speed/duplex mismatch, leave all ports on all switches at Full / 1000 (IRL we would set these to auto/auto)

Old CCSI here. I'll have to post response in chunks. Wasn't able to respond in one post. First: Disable Core switchports 3 - 8, Switch 2 port 6, Switch 3 ports 3, 5

On switch 3 port 4 both voice and wired user traffic are carried through on the same link, should that port be configured as a trunk link? since it needs to carry traffic from two different vlans?
