Cisco Switching/Routing :: 4948e - Data Sheet Is Not Supported
Feb 22, 2012
Cisco c4948e switch log is showing :
COMPACTFLASHNOTREADY: Compact flash is not ready

COMPACTFLASHNOTREADY: Compact flash is not readyFeb 24 00:28:22.338 UTC: %C4K_FLASH-4-COMPACTFLASHNOTREADY: Compact flash is not ready
Checked the data sheet and is not supported. Why we get this log from the switch? is it cosmetic?

I am using 10Gig link to connect distribution and access switches. Since we are terminating the cables at multiple locations, we are also doing the link budgeting. The CISCO SFP 10G-LR module data sheet shows two values for the transmit power one of which is maximum power .5dBm and another is minimum power -8.2 dBm. Which value should I choose for the link budgeting.

I have been asked to look at designing a network internally. I have no control of the upstream network besides requesting changes.Essentially I'm confused as to the best way to approach configuring the following and wondered if you could share any experiences. It's stretching the limits of a CCNA IMHO, although I understand a lot about networking this is one area where I'm a little sketchy.
Kit list:
4948-E-S or E-E switches.
Cisco ASA 5545 firewalls
Cisco ASA 5520 firewall
& Multiple L2 switches
- I have 3 subnets in total, a /29 for routing and two larger subnets routed to the /29
What I'm trying to do:
1) Have some hosts protected by the ASA 5545 firewalls, probably in routed mode (that's the confusing part). I cannot use NAT so the inside interface/VLAN would need public IP's.
2) Have some hosts not protected by the ASA, therefore straight out onto the public Internet with no firewall whatsoever, they connect directly to the L3 or to the L3 via a L2 switch.
3) Have the ASA 5520 take an IP from the public (non-protected range), as this will be a VPN endpoint too and will also need to have NAT enabled. This should be easy as it just takes an IP from a public subnet, the ASA 5545's are the tricky part as they cannot use NAT at all. I've also been advised not to use Transparent mode either.
4) L3 switches are essentially external switches, doing the routing for our subnets, before upstream.
5) Upstream provider provides gateway with HSRP, we're looking at using HSRP and a routing protocol on our side over two 4948 switches. Any recommendations on this?
6) Further to point 5, we do not currently have any ability to do BGP or anything. That would be done by a separate team, upstream.
Note: I've also got to justify the use of each IP to the network management team, they are quite stingy so I have to be careful that I don't waste too many IP's for core network. So what I'm thinking is I have to create subnetworks of my main subnets to break them up into smaller pieces, and then add some onto the inside interface of the ASA and others will be on the L3 switch. Then of course route the networks to the ASA outside IP. Saying that, I'm not clear if I should create a /29 or /30 to route to the outside of the ASA or grab one from the larger subnet as it were? The final outcome is that we can connect a machine directly to the Internet or behind a firewall, depending on the requirements for that individual device. All devices will have public IPs.

Using a 4948E switch with FastEthernet1 as the management interface which uses the VRF mgmtVrf. I cannot get DNS resolution to work for some reason.
I am using code enterprise 15.1-2.SG and here are the relevant config snippets:
ip domain-lookup source-interface FastEthernet1
ip domain-name domain.com
ip name-server 4.2.2.1
[Code].....
I read online there are some commands in a different code that support specifying the VRF along with the name servers, but I don't have those options. All I can do is set the source-interface on the domain-lookup command.

I am trying to setup SNMP v3 on a 4948E switch here is what I have done so far:
snmp-server location "location"
snmp-server contact IT Admins
snmp-server group SNMPgrp v3 priv read SNMP-ro write SNMP-rw access 80
snmp-server user snmp_user SNMPgrp v3 auth sha xxxxxxxxx priv aes 128 xxxxxxxx access 80
What else am I missing and how can I confirm that it is configured correctly?

I'm in the process to install two 4948E switches. I will be configuring GLBP and wanted to get some guidelines on configuring GLBP and EIGRP:
- First question is like HSRP I'm configuring it on both swithches like this:
Switch 1:
interface vlan 5
ip address 10.1.5.249 255.255.255.0
glbp 5 ip 10.1.5.1
glbp 5 priority 110
glbp 5 preempt
glbp 5 authentication md5 key-string xxxxxx
[code]....
- Second question is about EIGRP, when I configure EIGRP on the main switch that is AVG with the following commands, will I also have to run the same commands on the second 4948 E too?
router eigrp 10
network 10.1.5.0 255.255.255.0

I know the white papers say that the RPS 2300 supports the 3750-E series and the 3750 series, but we have 3750-G and -X series. Wanted to make sure that these switches are supported and if we need anything special?

From what I have found the VPN (WS-IPSEC-3) port adapter (on a WS-SSC-600) is not supported if you decide to turn the 6509-E into a VSS system.

Does GLC-GE-100FX is supported on the WS-C2960S-24TD-L. I don't see this switch listed under the compatibility matrix.URL
But the datasheet for the 2960S says this:
"The Cisco Catalyst 2960-S with SFP+ does not support the GLC-FE-100BX, GLC-FE-100FX, or GLC-FE-100LX." But it provides no reference for the GLC-GE-100FX The easy answer is, no the 2960S-24TD doesn't support it, any clarification if possible.

I would like to know whether WOL is supported on a N7K with 6.x code and F2 line cards. I also would like a how to for this. If it is not supported will an ip helper address to the broadcast address of the destination vlan SVI will suffice to get it workinng. If so I can restricht the forwarded broadcast to only the wol traffic.

I have a Cisco 1921 Router, a Cisco Catalyst 2960 and a Cisco Catalyst 2970 and I want the router to be able to assign ip-addresses by what VLAN a device is active on.
VLAN1: 10.0.0.0/24
VLAN2: 10.0.1.0/24
The router is connected to the Catalyst 2960 and there on to the Catalyst 2970 so the VLAN1 and VLAN2 is active on the to switches and the Router.is it possible?
