One of our client wants to know "How many route entries a 2821 router or 881 router can support" Such as the 3750 can support 11k routes in ‘desktop routing’ mode. But I want to know the limitations on routers.
I have the ME3400 deployed in an the following design. 8 100Meg ports connects to Cisco 2955s, and the 1Gig port uplinks to a Cisco 3560. My CDP neighbour table only shows an entries for the uplink Gig port. If I look at the CDP stats in the show cdp Interfaces Fastethernet 0/1,, I see CDP packets being sent every 60, but nothing returning.
On occasion I will have to clear the ARP cache on a 6500 when a customer swapeeds out a firewall or firewall NIC. The ARP cache will show the MAC of the previous device and will not update until either the ARP table refreshes dynamically (currenty at default time) or it is cleared manually.
Sometimes I need to clear it manually and sometimes is is refreshed dynamically when the new device comes up. Inconsistant issue....
Under what circimstances will an ARP entry NOT be refreshed when a firewall or firewall NIC is swapped out.
I want to upgrade my router but I need a router that supports more port forwarding entries for my applications. I have my eye on the WRT310N router but I need to know how big its port forwarding table is.
I am receiving this error after connecting a copper adapter on a GBIC blade in a 6509. Here are the results from the show Interface. I am waiting to confirm the device on the other side settings but as far as I see I get UP and Up for protocol and line respectively.
GigabitEthernet2/11 is up, line protocol is up (connected) Hardware is C6k 1000Mb 802.3, address is 0009.11e4.f3ce (bia 0009.11e4.f3ce) Description: RCPBSDEV MTU 1500 bytes, BW 1000000 Kbit, DLY 10 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation ARPA, loopback not set
Whats it "OfficeExtend support" in the 5500 WLC datasheet?.I dont see nothing about this in the WLC configuration guide release v22.214.171.124.Is this the same as OEAP?. Is the OfficeExtended (or OEAP) supported on the 1140 APs?. If so where can I get a guide to configure this?.
are there any AP models which support 5500 series and dont support 4400 series. Actually we are looking to get some new AP with higher bandwidth and External Antenna How to differentiate between AP models with clean air feature supported and not
I have two cisco asa firewalls connected through a VPN, one is 5505 and the other is a 5510. From the 5505 I can ping the internal interface of the 5510, but not vice versa. Would that be a NAT issue? I used the ASDM to configure the VPN tunnels with the wizard for IPsec site to site.
Is there an official Cisco-Page with the always-up-to-date recommended NX-OS-Releases for the Nexus 5000, just as there is URL
If there is no such page: What Release can be recommended?
We got new N596 & N2232 this week, and are using L2-LAN only, no L3,no FCoE- or FC-Ports. The command 'vPC orphan-ports suspend' is the newest feature used, so 5.0(3)N2(1) would be the oldest possible release.
Before I install 5.1(3)N1(1a) and then have to do a distruptive downgrade to 5.0(3)N2(2b), I'd like to be assured that the new one is already recommended as mature enough.
Having an issue with my WLC 5500 and client connectivity. This just started today. Clients will connect for a short period of time and then drop off. WLC appears fine with the exception of a bunch of trap errors. I've rebooted the WLC but this did not clear the issue.
how to configure the ASA 5500 with "Directed Broadcast" for Wake of lan from other networksegment. we want pass traffic from 192.168.10.0 network to 192.168.100.0 DMZ Network to turn on the server with Wake on Lan.
I read something about "Static NAT" but how do i make this one?
Are there any dependencies on VTP on the Nexus platforms like the 5500 or 7000? In IOS P V LAN required VTP Transparent mode however I cannot find any reference to this for the Nexus platform. Are there any other features that would require the use of VTP? By default VTP is turned off on nexus and has to be enabled with the feature command so is there any benefit to running VTP in transparent mode vs off?
There is very little and quite diverse Information regarding the if, where and how of a Nexus 5000 or 5500 series Switch and support for IEEE 802.1AE Link Layer Encryption (also called MACsec).
For example: the official FAQ denies that the Nexus 5500-series supports 802.1AE at all, while the data sheet says that only "downlink ports" are supported (host access).
On the Nexus 7000 platform the 802.1AE link layer encryption is part of TrustSec (feature cts) and much better documented.
The Question is: If and under which circumstances (configuration, L3 modules, license, NX/OS version) does a Nexus 5k or 5500 series Switch support 802.1AE on 1G or 10G interfaces that are directly connected to a Nexus 7000 (with the necessary cts feature licensed/configured)?
We have successfully peered two 5548UP switches together and separately we have successfully peered two 5596UP switches together. Works great and is our standard going forward for data center switching. I've been casting about Google and Cisco looking for an answer to this question:
Is it possible to have more than two 5500 class Nexus switches participate in a peered vPC configuration? For instance, can I connect a single FEX to four 5500 class switches in a vPC configuration? The question is more academic than actionable. Even if the answer is yes we probably wouldn't be in a position to implement something like this for a while.
I am experiencing inconsistent echo-replay from devices connected via VPC to Nexus 5500s while pinging from the Nexus exec prompt.
In some cases I receive normal response when pinging from one Nexus, but no response when pinging from the other switch. In other instance I receive normal response to one Nexus, and duplicate replays to the other. It looks like a VPC related bug. NXOS is 5.1.3.N2.1

Does the nexus 7010 support virtual switching yet? All of the posts I have found from about a year ago say that it is going to be supported, but there were no dates listed. I heard the same thing from Cisco a while back, but haven't followed up with it.If it is supported finally are there any configuration guides available for it?
Can any ASA 5500 in particular the ASA5510 firewall support jumbo frames (i.e. greater than the default standard 1500 Bytes frames)?. I plan to use the ASAs to setup a point-to-point IPSec tunnel and need an Application frame of 4Kbytes intact and not segment it.I have done little checking on the Cisco Website and see it mention of Jumbo frames on the 5580 on 10Gig interface but didn't see mention 5510. 5580s are way over-kill and expensive for what I need is to run a mission critical one IPSec point-to-point with maximum of no more than 100Kbps so 5510 is perfect for me but not sure if it can carry the jumbo frame?
On the routers and switches it's the MTU settings and they are configurable per interface and I am OK and the circuit is T1 which the Telcos said it's OK since it's physical layer so the only unkown is the firewall.
