Convert config from Cisco to HP??
I am trying to convert a config from a Cisco switch that is in production and working fine (but slow) to a gigabit HP switch.
I'm familar with Cisco networking, but not HP.
Can someone tell me why when I have this for the working Cisco config:
! version 12.0 no service pad service timestamps debug uptime service timestamps log uptime no service password-encryption ! hostname Commerce_Switch2 ! ! ! ! ! ! ! ip subnet-zero ! ! ! interface FastEthernet0/1 ! interface FastEthernet0/2 ! interface FastEthernet0/3 ! interface FastEthernet0/4 ! interface FastEthernet0/5 ! interface FastEthernet0/6 ! interface FastEthernet0/7 ! interface FastEthernet0/8 ! interface FastEthernet0/9 ! interface FastEthernet0/10 ! interface FastEthernet0/11 ! interface FastEthernet0/12 ! interface FastEthernet0/13 ! interface FastEthernet0/14 ! interface FastEthernet0/15 ! interface FastEthernet0/16 ! interface FastEthernet0/17 ! interface FastEthernet0/18 ! interface FastEthernet0/19 ! interface FastEthernet0/20 ! interface FastEthernet0/21 ! interface FastEthernet0/22 ! interface FastEthernet0/23 ! interface FastEthernet0/24 ! interface FastEthernet0/25 ! interface FastEthernet0/26 ! interface FastEthernet0/27 ! interface FastEthernet0/28 ! interface FastEthernet0/29 ! interface FastEthernet0/30 ! interface FastEthernet0/31 ! interface FastEthernet0/32 ! interface FastEthernet0/33 ! interface FastEthernet0/34 ! interface FastEthernet0/35 ! interface FastEthernet0/36 ! interface FastEthernet0/37 ! interface FastEthernet0/38 ! interface FastEthernet0/39 ! interface FastEthernet0/40 ! interface FastEthernet0/41 ! interface FastEthernet0/42 ! interface FastEthernet0/43 ! interface FastEthernet0/44 ! interface FastEthernet0/45 ! interface FastEthernet0/46 ! interface FastEthernet0/47 ! interface FastEthernet0/48 ! interface GigabitEthernet0/1 ! interface GigabitEthernet0/2 switchport trunk encapsulation dot1q switchport mode trunk ! interface VLAN1 ip address 164.165.71.52 255.255.255.0 no ip directed-broadcast no ip route-cache ! ip default-gateway 164.165.71.1 ! line con 0 transport input none stopbits 1 line vty 0 4 login line vty 5 15 login ! end
And I have this for the HP switch:
Running configuration: ; J4865A Configuration Editor; Created on release #G.07.70 hostname "CommerceGigabit" time timezone -480 cdp run module 2 type J4862B module 4 type J4908A module 6 type J4908A module 8 type J4908A ip default-gateway 164.165.71.1 ip routing snmp-server community "public" Unrestricted vlan 1 name "DEFAULT_VLAN" untagged B1-B24,D1-D22,F1-F22,H1-H22 ip address 164.165.71.52 255.255.255.0 exit
I would like to use the port d20 as a trunk port to the trunk port on the other end (connected to a Cisco switch).
When I connect the network cable to D20, I am able to ping the gateway, but if I connect any other computer to port D1, I don't get a DHCP address, and if I'm on the HP switch, I can't ping anything past the gateway itself.......
Can anyone assit??

Re: Convert config from Cisco to HP??
I would remove "ip routing" from the HP config since Im guessing this is actually not a router but a pure L2 switch. Since you are able to communicate with the default gateway the L2 stuff actually works, might be the "ip routing" that interferes.

Re: Convert config from Cisco to HP??
I actually added in the IP routing after determining that the HP config didn't allow me to get outside our network.
I also had experimented with tagging and untagging port D20 (the trunk port), and the only way I could ping my gateway was to leave D20 untagged.
But again if I connect a laptop to D1, I don't get a DHCP address, can't do anything on the network.......
Thinking something must not be right :(

Re: Convert config from Cisco to HP??
Also when you add "ip routing" the "ip default-gateway" command looses its effect.

Re: Convert config from Cisco to HP??
So why, if the ip routing command isn't there, would a computer plugged into D1 not be able to connect and get a DHCP address???

From the specs I can see, yes, it is a layer 2 switch. Its a 4108gl

Re: Convert config from Cisco to HP??
Start with an upgrade to the newest SW G.07.117. As I can't really see any obvious fault in your config maybe its a bug.
Do you see mac adresses both ways?

Re: Convert config from Cisco to HP??
Well, I am making SOME progress :)
I changed
vlan 1 name "DEFAULT_VLAN" untagged B1-B24,D1-D22,F1-F22,H1-H22 ip address 164.165.71.52 255.255.255.0 exit
to instead get the IP address from DHCP, and then connected a laptop to port D1, and the trunk port to D20. I can now get a IP address on the laptop, and get to the internet, so that's good.
I'm a little confused, from the command line of the HP if I ping the IP address of the laptop in D1, it says the laptop failed to respond...... and I can't ping from the laptop to the IP assigned to VLAN1.
Also, from my desktop (not connected to the HP switch) I am unable to ping to a IP address connected to the HP switch....... or the other way, from the switch to my desktop.......
Its all 1 IP range, we have the full class C, so we're not dealing with a routing issue I don't believe.......
So updating the software on the HP via tftp becomes sorta hard......any idea why I can't ping across the same module??

Re: Convert config from Cisco to HP??
That doesn't really make much sense.
Remove the IP address from the HP switch - it's just confusing and distracting you.
It's a switch: it doesn't use an IP address to do its switching.
Obviously, remove "ip routing".
Now, check your Layer2 is all OK:
- VLAN exists on both switches
- VLAN added to both sides of the Switch-switch link
- VLAN is UNTAGGED on both sides (or, TAGGED on both sides)
Test: enable CDP on the HP switch (or LLDP on the Cisco switch), issue a "show cdp nei" (or "sh lldp inf rem").
- Switches should see each other.
Next, check Layer 3 is OK:
- Host address in correct subnet
- Host mask OK
- Host gateway address is the IP address ... where?
- Gateway address is correct
- Host can ping its gateway when patched to cisco switch
- Obviously, this mean host can ping its gateway when patched to HP switch (else, back to Layer2 with you!)
