This read-only Gauge reports the desired starting bandwidth, in bits per second, that the device attempts to establish when first calling this peer, applicable only to dial-type connections and not leased circuits; the system brings up enough connections to meet this target. An admin sets expectations using this value for how quickly a bandwidth-on-demand link should reach its baseline capacity. For example, an initial bandwidth of 64000 tells the admin the device will bring up enough dial channels to reach 64 kbps as soon as the call to this peer begins, before scaling further if demand grows.
