Hey Leo, *Agreed, there appears to be so much documentation at times, all for the same stuff, that it makes it VERY difficult to find the answer that your looking for... I'm still not seeing the limitation for the 4510R+E (*Hardware Revision = 1.0) not having the ability to use Sup8-E. The limitation that I keep seeing appears to be for 4507R-E, which needs to be Hardware Revision = 2.0. So I opened a TAC case yesterday and they had confirmed that with our 4510R+E chassis, that we can upgrade to Sup8-E, we just wouldn't be able to upgrade to the Sup9-E.   Thanks Again, Matt ...

Thanks Leo. So that command shows: #show idprom chassis | inc Hardware Hardware Revision = 1.0 I'm looking at a few different pages showing Sup8 Compatibility, and the only thing in all those pages that even mentions Hardware revision or Hardware version is that the USB ports of the Sup8 are only supported on Hardware Revision = 1.1... Do you know where I can find this documented for 4500 Chassis compatibility ? So far I have not been able to find this specification for Hardware Revision. On a few pages showing the Installation and Configuration guide for Sup8, it shows: 1.To support Supervisor Engine 8-E and 8L-E, the Cisco Catalyst 4507R-E Switch chassis must have hardware revision 2.0 or higher. Note that the hardware revision is with reference to the chassis and not the supervisor engine. It's not stating the same requirement for the 4510R+E... Thanks Again, Matt ... View more

Couldn't find any EOL announcements for the Sup8 or Sup9, so I assume those haven't been announced yet..? Also, it looks like the newest IOS-XE versions for both Sup8-E and Sup9-E is version 3.11.0E Basically, we're trying to get a few more years our of our existing 4510R+E and are trying to decide which way we should go, as Sup8's are significantly cheaper. We are currently running a redundant pair of WS-X45-SUP7-E. Our existing Linecards include: WS-X45-SUP7-E x 2 WS-X4648-RJ45-E x 2 WS-X4648-RJ45V+E x 2 WS-X4548-GB-RJ45V x 3 Thanks Again, Matt ...

Any ideas why this wouldn't be working and I'm still seeing a DNS Server once its connected via DHCP? -Matt ... View more

Hey Hector, So this past weekend I attempted this fix for the dhcp interface. But, it appears to still be showing the DNS servers coming through for that interface. I added the following to the interface: #show run int Gi0/0/0 Building configuration... Current configuration : 317 bytes ! interface GigabitEthernet0/0/0 description Broadband Internet Gateway no ip dhcp client request domain-name no ip dhcp client request dns-nameserver ip dhcp client client-id GigabitEthernet0/0/0 ip address dhcp ip nat outside zone-member security INTERNET media-type rj45 negotiation auto end I then did a "release dhcp GigabitEthernet 0/0/0", then I did "renew dhcp GigabitEthernet 0/0/0". And after that I ran the "show ip dns servers" command, and it was still showing that interface's DNS servers that its getting via DHCP. So I then tried to do a "shut", then "no shut" on the interface. And after the interface came back up, I'm still seeing those DNS servers... Any idea what could be going wrong here?   Thanks Again, Matt ... View more

Ok that's what I figured. I'll perform that tonight. Also, would the "release/renew dhcp Gi 0/0/0" do it as well? Or is that only for the dhcp server on the Router itself? -Matt ... View more

Any idea if I'll need to reset the interface (*shut/no shut) after adding that command to the int? -Matt ... View more

Thanks Hector! Yes, so with those first 2 commands, it does look like it is receiving a DNS server from that interface. I'll give that other command a try and see if that works to disable DNS server from the dhcp interface. Thanks Again, Matt ... View more
