What is a load interval?
the load interval provides a time interval used for calculation of. packets /s. bytes /s. both input and output direction. These counters do not provide the instant value they are rather an exponentially weighted average.
What is load interval 30 cisco?
The IOS calculates statistics (including load) over some interval which can be controlled using the load-interval command. 30 seconds is the smallest interval that can be configured. There may be advantages to longer intervals and advantages to shorter intervals.
What does no ip redirects do?
no ip redirects–this disables icmp redirect messages. Redirects happen when a router recognizes a packet arriving on an interface and the best route is out that same interface. In that case the router sends an icmp redirect back to the source telling them about a better router on the same subnet.
What is Mroute cache?
Description. This command enables fast switching for multicast routing, which is analogous to the route cache for unicast routing. If disabled with the no form of the command, every packet is switched at the process level.
How Does Proxy ARP Work?
Proxy ARP is a technique by which a proxy server on a given network answers the Address Resolution Protocol (ARP) queries for an IP address that is not on that network. The proxy is aware of the location of the traffic’s destination and offers its own MAC address as the (ostensibly final) destination.
How do I delete a multicast route?
If you specify the IPv4 address of a multicast group and the IPv4 address of a multicast source, the router clears the multicast forwarding entry that matches that group and source. To delete IP multicast forwarding entries issue the clear ip mroute command in Privileged Exec mode.
What is no IP Mroute cache?
It disables fast switching of multicast packet on the interface on the Cisco router. Check.
How do I remove an IP route from a Cisco router?
To remove static routes, use the no form of this command.
- ip route prefix mask ip-address [metric-value]
- no ip route prefix mask ip-address.
- Syntax Description.
- Command Default.
- Command Modes.
- Command History.
- Modification.
- Release.
What is RARP and bootp?
BOOTP (Bootstrap Protocol) is the successor of RARP (Reverse ARP) and the predecessor of DHCP. RARP is a link layer protocol and the problem of RARP is that you can’t route these packets. You need a RARP server on every subnet. BOOTP uses the UDP transport protocol and rides on top of IP so it can be routed.
What are the 4 types of ARP?
Types of ARP
- Proxy ARP.
- Gratuitous ARP.
- Reverse ARP.
- Inverse ARP.
What is ICMP and IGMP?
The major distinction between ICMP(Internet Control Message Protocol) and IGMP(Internet Group Message Protocol) is that, IGMP is employed to form cluster of hosts, whereas ICMP is employed to send error messages and operational data indicating by hosts.
What is floating route in Cisco?
A floating static route is used as a backup route. It has a manually configured administrative distance greater than that of the primary route and therefore would not be in the routing table until the primary route fails. You will test failover to the backup route, and then restore connectivity to the primary route.
What is APR and RARP?
ARP stands for Address Resolution Protocol. Whereas RARP stands for Reverse Address Resolution Protocol. 2. Through ARP, (32-bit) IP address mapped into (48-bit) MAC address. Whereas through RARP, (48-bit) MAC address of 48 bits mapped into (32-bit) IP address.
What is BOOTP vs DHCP?
The major difference between BOOTP and DHCP is that BOOTP support static configuration of the IP addresses while DHCP supports dynamic configuration. It means that DHCP automatically assigns and obtain the IP addresses from the computer connected to the internet and also have some additional features.
