Question: (not sure about the requirement, I will try to update soon!)
Answer and Explanation:
Below is a good solution commented by toy_man123. Please say thank to him!
Each of these vlans has one host each on its port
SVI on vlan 1 - ip 192.168.1.11 with snm
Switch B -
Ports 3, 4 connected to ports 3 and 4 on Switch A
Port 15 connected to Port on Router.
Tasks to do
1. Use non proprietary mode of aggregation with Switch B being the initiator
-- Assumed use LACP with B being in Active mode
2. Use non proprietary trunking and no negotiation
-- Assumed use switchport mode trunk and switchport trunk encapsulation dot1q
3. Restrict only to vlans needed
-- Assumed either vtp pruning or allowed vlan list. vtp pruning command did not seem to work on the simulator so landed using allowed vlan list
4. SVI on vlan 1 with some ip and subnet given
5. Configure switch A so that nodes other side of Router C are accessible
-- Assumed this to mean that on switch A default gatway has to be configured.
6. Make switch B the root
-- Could not get this to work. Exam hung when I tried the command
spanning-tree vlan 1,21-23 priority 4096
So passed on this configuration. Anyone else got this correct
What I tried ..
on Switch A
verify with show run if you need to create vlans 21-23
int range fa0/9 - 10
switchport mode access
switchport access vlan 21
spanning-tree portfast
no shut
int range fa0/13 - 14
switchport mode access
switchport access vlan 22
spanning-tree portfast
no shut
int range fa0/16 - 16
switchport mode access
switchport access vlan 23
spanning-tree portfast
no shut
int range fa0/3 - 4
channel-protocol lacp
channel group 1 mode passive
no shut
int port-channel 1
switchport mode trunk
switchport trunk encapsulation dot1q
spanning-tree allowed vlans 1,21-23
no shut
int vlan 1
ip address x.y.z.11 255.a.b.c
no shut
On switch B run the command show cdp neighbors detail and get the ip address of port from router C.
Now use this ip address of port of router C to configure as default gateway on Switch A
SA(config)# ip default-gateway 192.168.1.1
On switch B do only the channel group and port-channel stuff
Only mode is active instead of passive.
copy run start did not work. Tried combos of wr, copy running-config startup-config, copy system:running-config nvram:startup-config. All variations did not work.
Got some errors on mismatch of native VLAN. Switch B had some ports on vlan 98 configured for native vlan. Tried setting native vlan on Port-channel 1 on switch B to 1. Configuration command took but errors still were occuring. Ran out of time I had allocated so gave up.
